This update provides the\n corresponding updates for ssl-cert -- potentially compromised snake-oil\n SSL certificates will be regenerated.\n\n Original advisory details:\n \n A weakness has been discovered in the random number generator used\n by OpenSSL on Debian and Ubuntu systems. As a result of this\n weakness, certain encryption keys are much more common than they\n should be, such that an attacker could guess the key through a\n brute-force attack given minimal knowledge of the system. This\n particularly affects the use of encryption keys in OpenSSH, OpenVPN\n and SSL certificates.\n \n This vulnerability only affects operating systems which (like\n Ubuntu) are based on Debian. However, other systems can be\n indirectly affected if weak keys are imported into them.\n \n We consider this an extremely serious vulnerability, and urge all\n users to act immediately to secure their systems.

However, other systems\ncan be indirectly affected if weak keys are imported into them.\n\nIt is strongly recommended that all cryptographic key material which has\nbeen generated by OpenSSL versions starting with 0.9.8c-1 on Debian\nsystems is recreated from scratch. Furthermore, all DSA keys ever used\non affected Debian systems for signing or authentication purposes should\nbe considered compromised; the Digital Signature Algorithm relies on a\nsecret random value used during signature generation.\n\nThe first vulnerable version, 0.9.8c-1, was uploaded to the unstable\ndistribution on 2006-09-17, and has since propagated to the testing and\ncurrent stable (etch) distributions.

As a result,\nall user and host keys generated using broken versions of the openssl\npackage must be considered untrustworthy, even after the openssl\nupdate has been applied.\n\n1. Install the security updates\n\nThis update contains a dependency on the openssl update and will\nautomatically install a corrected version of the libssl0.9.8 package,\nand a new package openssh-blacklist.\n\nOnce the update is applied, weak user keys will be automatically\nrejected where possible (though they cannot be detected in all cases).\nIf you are using such keys for user authentication, they will\nimmediately stop working and will need to be replaced (see step 3).\n\nOpenSSH host keys can be automatically regenerated when the OpenSSH\nsecurity update is applied. The update will prompt for confirmation\nbefore taking this step.\n\n2. Update OpenSSH known_hosts files\n\nThe regeneration of host keys will cause a warning to be displayed\nwhen connecting to the system using SSH until the host key is updated\nin the known_hosts file. The warning will look like this :\n\n@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING:\nREMOTE HOST IDENTIFICATION HAS CHANGED! @\n@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS\nPOSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be\neavesdropping on you right now (man-in-the-middle attack)! It is also\npossible that the RSA host key has just been changed.\n\nIn this case, the host key has simply been changed, and you should\nupdate the relevant known_hosts file as indicated in the error\nmessage. It is recommended that you use a trustworthy channel to\nexchange the server key. It is found in the file\n/etc/ssh/ssh_host_rsa_key.pub on the server; it's fingerprint can be\nprinted using the command :\n\nssh-keygen -l -f /etc/ssh/ssh_host_rsa_key.pub\n\nIn addition to user-specific known_hosts files, there may be a\nsystem-wide known hosts file /etc/ssh/ssh_known_hosts. This is file is\nused both by the ssh client and by sshd for the hosts.equiv\nfunctionality. This file needs to be updated as well.\n\n3. Check all OpenSSH user keys\n\nThe safest course of action is to regenerate all OpenSSH user keys,\nexcept where it can be established to a high degree of certainty that\nthe key was generated on an unaffected system.\n\nCheck whether your key is affected by running the ssh-vulnkey tool,\nincluded in the security update. By default, ssh-vulnkey will check\nthe standard location for user keys (~/.ssh/id_rsa, ~/.ssh/id_dsa and\n~/.ssh/identity), your authorized_keys file (~/.ssh/authorized_keys\nand ~/.ssh/authorized_keys2), and the system's host keys\n(/etc/ssh/ssh_host_dsa_key and /etc/ssh/ssh_host_rsa_key).\n\nTo check all your own keys, assuming they are in the standard\nlocations (~/.ssh/id_rsa, ~/.ssh/id_dsa, or ~/.ssh/identity) :\n\nssh-vulnkey\n\nTo check all keys on your system :\n\nsudo ssh-vulnkey -a\n\nTo check a key in a non-standard location :\n\nssh-vulnkey /path/to/key\n\nIf ssh-vulnkey says 'Unknown (no blacklist information)', then it has\nno information about whether that key is affected. In this case, you\ncan examine the modification time (mtime) of the file using 'ls -l'.\nKeys generated before September 2006 are not affected. Keep in mind\nthat, although unlikely, backup procedures may have changed the file\ndate back in time (or the system clock may have been incorrectly set).\nIf in doubt, generate a new key and remove the old one from any\nservers.\n\n4. Regenerate any affected user keys\n\nOpenSSH keys used for user authentication must be manually\nregenerated, including those which may have since been transferred to\na different system after being generated.\n\nNew keys can be generated using ssh-keygen, e.g. :\n\n $ ssh-keygen Generating public/private rsa key pair. Enter file in\n which to save the key (/home/user/.ssh/id_rsa): Enter passphrase\n (empty for no passphrase): Enter same passphrase again: Your\n identification has been saved in /home/user/.ssh/id_rsa. Your\n public key has been saved in /home/user/.ssh/id_rsa.pub. The key\n fingerprint is: 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00\n user@host\n\n5. Update authorized_keys files (if necessary)\n\nOnce the user keys have been regenerated, the relevant public keys\nmust be propagated to any authorized_keys files (and authorized_keys2\nfiles, if applicable) on remote systems. Be sure to delete the lines\ncontaining old keys from those files.\n\nIn addition to countermeasures to mitigate the randomness\nvulnerability, this OpenSSH update fixes several other vulnerabilities\n:\n\n CVE-2008-1483: Timo Juhani Lindfors discovered that, when using X11\n forwarding, the SSH client selects an X11 forwarding port without\n ensuring that it can be bound on all address families.

------------------------------------------------------------------------\nDebian Security Advisory DSA-1571-1 security@debian.org\nhttp://www.debian.org/security/ Florian Weimer\nMay 13, 2008 http://www.debian.org/security/faq\n- ------------------------------------------------------------------------\n\nPackage : openssl\nVulnerability : predictable random number generator\nProblem type : remote\nDebian-specific: yes\nCVE Id(s) : CVE-2008-0166\n\nLuciano Bello discovered that the random number generator in Debian&#x27;s\nopenssl package is predictable. This is caused by an incorrect\nDebian-specific change to the openssl package (CVE-2008-0166). As a\nresult, cryptographic key material may be guessable.\n\nThis is a Debian-specific vulnerability which does not affect other\noperating systems which are not based on Debian. However, other systems\ncan be indirectly affected if weak keys are imported into them.\n\nIt is strongly recommended that all cryptographic key material which has\nbeen generated by OpenSSL versions starting with 0.9.8c-1 on Debian\nsystems is recreated from scratch. Furthermore, all DSA keys ever used\non affected Debian systems for signing or authentication purposes should\nbe considered compromised; the Digital Signature Algorithm relies on a\nsecret random value used during signature generation.\n\nThe first vulnerable version, 0.9.8c-1, was uploaded to the unstable\ndistribution on 2006-09-17, and has since propagated to the testing and\ncurrent stable (etch) distributions. The old stable distribution\n(sarge) is not affected.\n\nAffected keys include SSH keys, OpenVPN keys, DNSSEC keys, and key\nmaterial for use in X.509 certificates and session keys used in SSL/TLS\nconnections. Keys generated with GnuPG or GNUTLS are not affected,\nthough.\n\nA detector for known weak key material will be published at:\n\n &lt;http://security.debian.org/project/extra/dowkd/dowkd.pl.gz&gt;\n &lt;http://security.debian.org/project/extra/dowkd/dowkd.pl.gz.asc&gt;\n (OpenPGP signature)\n\nInstructions how to implement key rollover for various packages will be\npublished at:\n\n &lt;http://www.debian.org/security/key-rollover/&gt;\n\nThis web site will be continously updated to reflect new and updated\ninstructions on key rollovers for packages using SSL certificates.\nPopular packages not affected will also be listed.\n\nIn addition to this critical change, two other vulnerabilities have been\nfixed in the openssl package which were originally scheduled for release\nwith the next etch point release: OpenSSL&#x27;s DTLS (Datagram TLS,\nbasically &quot;SSL over UDP&quot;) implementation did not actually implement the\nDTLS specification, but a potentially much weaker protocol, and\ncontained a vulnerability permitting arbitrary code execution\n(CVE-2007-4995). A side channel attack in the integer multiplication\nroutines is also addressed (CVE-2007-3108).\n\nFor the stable distribution (etch), these problems have been fixed in\nversion 0.9.8c-4etch3.\n\nFor the unstable distribution (sid) and the testing distribution\n(lenny), these problems have been fixed in version 0.9.8g-9.\n\nWe recommend that you upgrade your openssl package and subsequently\nregenerate any cryptographic material, as outlined above.\n\nUpgrade instructions\n- --------------------\n\nwget url\n will fetch the file for you\ndpkg -i file.deb\n will install the

------------------------------------------------------------------------\nDebian Security Advisory DSA-1576-1 security@debian.org\nhttp://www.debian.org/security/ Florian Weimer\nMay 14, 2008 http://www.debian.org/security/faq\n- ------------------------------------------------------------------------\n\nPackage : openssh\nVulnerability : predictable random number generator\nProblem type : remote\nDebian-specific: yes\nCVE Id(s) : CVE-2008-0166\n\nThe recently announced vulnerability in Debian&#x27;s openssl package\n(DSA-1571-1, CVE-2008-0166) indirectly affects OpenSSH. As a result,\nall user and host keys generated using broken versions of the openssl\npackage must be considered untrustworthy, even after the openssl update\nhas been applied.\n\n1. Install the security updates\n\n This update contains a dependency on the openssl update and will\n automatically install a corrected version of the libss0.9.8 package,\n and a new package openssh-blacklist.\n\n Once the update is applied, weak user keys will be automatically\n rejected where possible (though they cannot be detected in all\n cases). If you are using such keys for user authentication, they\n will immediately stop working and will need to be replaced (see\n step 3).\n\n OpenSSH host keys can be automatically regenerated when the OpenSSH\n security update is applied. The update will prompt for confirmation\n before taking this step.\n\n2. Update OpenSSH known_hosts files\n\n The regeneration of host keys will cause a warning to be displayed when\n connecting to the system using SSH until the host key is updated in the\n known_hosts file. The warning will look like this:\n\n @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@\n @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @\n @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@\n IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!\n Someone could be eavesdropping on you right now (man-in-the-middle attack)!\n It is also possible that the RSA host key has just been changed.\n\n In this case, the host key has simply been changed, and you should update\n the relevant known_hosts file as indicated in the error message.\n \n It is recommended that you use a trustworthy channel to exchange the\n server key. It is found in the file /etc/ssh/ssh_host_rsa_key.pub on\n the server; it&#x27;s fingerprint can be printed using the command:\n\n ssh-keygen -l -f /etc/ssh/ssh_host_rsa_key.pub\n\n In addition to user-specific known_hosts files, there may be a\n system-wide known hosts file /etc/ssh/known_hosts. This is file is\n used both by the ssh client and by sshd for the hosts.equiv\n functionality. This file needs to be updated as well.\n\n3. Check all OpenSSH user keys\n\n The safest course of action is to regenerate all OpenSSH user keys,\n except where it can be established to a high degree of certainty that the\n key was generated on an unaffected system.\n\n Check whether your key is affected by running the ssh-vulnkey tool, included\n in the security update. By default, ssh-vulnkey will check the standard\n location for user keys (~/.ssh/id_rsa, ~/.ssh/id_dsa and ~/.ssh/identity),\n your authorized_keys file (~/.ssh/authorized_keys and\n ~/.ssh/authorized_keys2), and the system&#x27;s host keys\n (/etc/ssh/ssh_host_dsa_key and /etc/ssh/ssh_host_rsa_key).\n\n To check all your own keys, assuming they are in the standard\n locations (~/.ssh/id_rsa, ~/.ssh/id_dsa, or ~/.ssh/identity):\n\n ssh-vulnkey\n\n To check all keys on your system:\n\n sudo ssh-vulnkey -a\n\n To check a key in a non-standard location:\n\n ssh-vulnkey /path/to/key\n\n If ssh-vulnkey says &quot;Unknown (no blacklist information)&quot;, then it has no\n information about whether that key is affected. In this case, you\n can examine the modification time (mtime) of the file using &quot;ls -l&quot;.\n Keys generated before September 2006 are not affected. Keep in mind\n that, although unlikely, backup procedures may have changed the file\n date back in time (or the system clock may have been incorrectly\n set).\n \n If in doubt, generate a new key and remove the old one from any\n servers.\n\n4. Regenerate any affected user keys\n\n OpenSSH keys used for user authentication must be manually regenerated,\n including those which may have since been transferred to a different system\n after being generated.\n\n New keys can be generated using ssh-keygen, e.g.:\n\n $ ssh-keygen\n Generating public/private rsa key pair.\n Enter file in which to save the key (/home/user/.ssh/id_rsa):\n Enter passphrase (empty for no passphrase):\n Enter same passphrase again:\n Your identification has been saved in /home/user/.ssh/id_rsa.\n Your public key has been saved in /home/user/.ssh/id_rsa.pub.\n The key fingerprint is:\n 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 user@host\n\n5. Update authorized_keys files (if necessary)\n\n Once the user keys have been regenerated, the relevant public keys\n must be propagated to any authorized_keys files (and authorized_keys2\n files, if applicable) on remote systems. Be sure to delete the lines\n containing old keys from those files..\n\n\nIn addition to countermeasures to mitigate the randomness vulnerability,\nthis OpenSSH update fixes several other vulnerabilities:\n\nCVE-2008-1483:\n Timo Juhani Lindfors discovered that, when using X11 forwarding, the\n SSH client selects an X11 forwarding port without ensuring that it\n can be bound on all address families. If the system is configured\n with IPv6 (even if it does not have working IPv6 connectivity), this\n could allow a local attacker on the remote server to hijack X11\n forwarding.\n\nCVE-2007-4752:\n Jan Pechanec discovered that ssh fails back to creating a trusted X11\n cookie if creating an untrusted cookie fails, potentially exposing\n the local display to a malicious remote server when using X11\n forwarding.\n\nFor the stable distribution (etch), these problems have been fixed in\nversion 4.3p2-9etch1. Currently, only a subset of all supported\narchitectures have been built; further updates will be provided when\nthey become available.\n\nFor the unstable distribution (sid) and the testing distribution\n(lenny), these problems have been fixed in version 4.7p1-9.\n\nWe recommend that you upgrade your openssh packages and take the\nmeasures indicated above.\n\nUpgrade instructions\n- --------------------\n\nwget url\n will fetch the file for you\ndpkg -i file.deb\n will install the referenced file.\n\nIf you are using the apt-get package manager, use the line for\nsources.list as given below:\n\napt-get update\n will update the internal database\napt-get upgrade\n will install corrected packages\n\nYou may use an automated update by adding the resources from the\nfooter to the proper configuration.\n\n\nDebian GNU/Linux 4.0 alias etch\n- -------------------------------\n\nSource archives:\n\n

As a result of this\r\nweakness, certain encryption keys are much more common than they\r\nshould be, such that an attacker could guess the key through a\r\nbrute-force attack given minimal knowledge of the system. This\r\nparticularly affects the use of encryption keys in OpenSSH, OpenVPN\r\nand SSL certificates.\r\n\r\nThis vulnerability only affects operating systems which &#40;like\r\nUbuntu&#41; are based on Debian. However, other systems can be\r\nindirectly affected if weak keys are imported into them.\r\n\r\nWe consider this an extremely serious vulnerability, and urge all\r\nusers to act immediately to secure their systems. &#40;CVE-2008-0166&#41;\r\n\r\nThis advisory also applies to the corresponding versions of\r\nKubuntu, Edubuntu, and Xubuntu.\r\n\r\n== Who is affected ==\r\n\r\nSystems which are running any of the following releases:\r\n\r\n * Ubuntu 7.04 &#40;Feisty&#41;\r\n * Ubuntu 7.10 &#40;Gutsy&#41;\r\n * Ubuntu 8.04 LTS &#40;Hardy&#41;\r\n * Ubuntu &quot;Intrepid Ibex&quot; &#40;development&#41;: libssl &lt;= 0.9.8g-8\r\n * Debian 4.0 &#40;etch&#41; &#40;see corresponding Debian security advisory&#41;\r\n\r\nand have openssh-server installed or have been used to create an\r\nOpenSSH key or X.509 &#40;SSL&#41; certificate.\r\n\r\nAll OpenSSH and X.509 keys generated on such systems must be\r\nconsidered untrustworthy, regardless of the system on which they\r\nare used, even after the update has been applied.\r\n\r\nThis includes the automatically generated host keys used by OpenSSH,\r\nwhich are the basis for its server spoofing and man-in-the-middle\r\nprotection.\r\n\r\nThe problem can be corrected by upgrading your system to the\r\nfollowing package versions:\r\n\r\nUbuntu 7.04:\r\n libssl0.9.8 0.9.8c-4ubuntu0.3\r\n\r\nUbuntu

\r\nUbuntu Security Notice USN-612-2 May 13, 2008\r\nopenssh vulnerability\r\nCVE-2008-0166, http://www.ubuntu.com/usn/usn-612-1\r\n===========================================================\r\n\r\nA weakness has been discovered in the random number generator used\r\nby OpenSSL on Debian and Ubuntu systems. As a result of this\r\nweakness, certain encryption keys are much more common than they\r\nshould be, such that an attacker could guess the key through a\r\nbrute-force attack given minimal knowledge of the system. This\r\nparticularly affects the use of encryption keys in OpenSSH.\r\n\r\nThis vulnerability only affects operating systems which &#40;like\r\nUbuntu&#41; are based on Debian. However, other systems can be\r\nindirectly affected if weak keys are imported into them.\r\n\r\nWe consider this an extremely serious vulnerability, and urge all\r\nusers to act immediately to secure their systems.\r\n\r\nThe following Ubuntu releases are affected:\r\n\r\nUbuntu 7.04\r\nUbuntu 7.10\r\nUbuntu 8.04 LTS\r\n\r\nThis advisory also applies to the corresponding versions of\r\nKubuntu, Edubuntu, and Xubuntu.\r\n\r\n\r\nUpdating your system:\r\n\r\n1. Install the security updates\r\n\r\n Ubuntu 7.04:\r\n openssh-client 1:4.3p2-8ubuntu1.3\r\n openssh-server 1:4.3p2-8ubuntu1.3\r\n\r\n Ubuntu 7.10:\r\n openssh-client 1:4.6p1-5ubuntu0.3\r\n openssh-server 1:4.6p1-5ubuntu0.3\r\n\r\n Ubuntu 8.04 LTS:\r\n openssh-client 1:4.7p1-8ubuntu1.1\r\n openssh-server 1:4.7p1-8ubuntu1.1\r\n\r\n Once the update is applied, weak user keys will be automatically\r\n rejected where possible &#40;though they cannot be detected in all\r\n cases&#41;. If you are using such keys for user authentication,\r\n they will immediately stop working and will need to be replaced\r\n &#40;see step 3&#41;.\r\n\r\n OpenSSH host keys can be automatically regenerated when the\r\n OpenSSH security update is applied. The update will prompt for\r\n confirmation before taking this step.\r\n\r\n2. Update OpenSSH known_hosts files\r\n\r\n The regeneration of host keys will cause a warning to be displayed\r\n when connecting to the system using SSH until the host key is\r\n updated in the known_hosts file. The warning will look like this:\r\n\r\n @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@\r\n @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @\r\n @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@\r\n IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!\r\n Someone could be eavesdropping on you right now &#40;man-in-the-middle\r\n attack&#41;! It is also possible that the RSA host key has just been\r\n changed.\r\n\r\n In this case, the host key has simply been changed, and you\r\n should update the relevant known_hosts file as indicated in the\r\n error message.\r\n\r\n3. Check all OpenSSH user keys\r\n\r\n The safest course of action is to regenerate all OpenSSH user\r\n keys, except where it can be established to a high degree of\r\n certainty that the key was generated on an unaffected system.\r\n\r\n Check whether your key is affected by running the ssh-vulnkey\r\n tool, included in the security update. By default, ssh-vulnkey\r\n will check the standard location for user keys &#40;~/.ssh/id_rsa,\r\n ~/.ssh/id_dsa and ~/.ssh/identity&#41;, your authorized_keys file\r\n &#40;~/.ssh/authorized_keys and ~/.ssh/authorized_keys2&#41;, and the\r\n system&#39;s host keys &#40;/etc/ssh/ssh_host_dsa_key and\r\n /etc/ssh/ssh_host_rsa_key&#41;.\r\n\r\n To check all your own keys, assuming they are in the standard\r\n locations &#40;~/.ssh/id_rsa, ~/.ssh/id_dsa, or ~/.ssh/identity&#41;:\r\n\r\n $ ssh-vulnkey\r\n\r\n To check all keys on your system:\r\n\r\n $ sudo ssh-vulnkey -a\r\n\r\n To check a key in a non-standard location:\r\n\r\n $ ssh-vulnkey /path/to/key\r\n\r\n If ssh-vulnkey says &quot;Unknown &#40;no blacklist information&#41;&quot;,\r\n then it has no information about whether that key is affected.\r\n If in doubt, destroy the key and generate a new one.\r\n\r\n4. Regenerate any affected user keys\r\n\r\n OpenSSH keys used for user authentication must be manually\r\n regenerated, including those which may have since been\r\n transferred to a different system after being generated.\r\n\r\n New keys can be generated using ssh-keygen, e.g.:\r\n\r\n $ ssh-keygen\r\n Generating public/private rsa key pair.\r\n Enter file in which to save the key &#40;/home/user/.ssh/id_rsa&#41;:\r\n Enter passphrase &#40;empty for no passphrase&#41;:\r\n Enter same passphrase again:\r\n Your identification has been saved in /home/user/.ssh/id_rsa.\r\n Your public key has been saved in /home/user/.ssh/id_rsa.pub.\r\n The key fingerprint is:\r\n 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 user@host\r\n\r\n5. Update authorized_keys files &#40;if necessary&#41;\r\n\r\n Once the user keys have been regenerated, the relevant public\r\n keys must be propagated to any authorized_keys files on\r\n remote systems. Be sure to delete the affected key.\r\n\r\n\r\nUpdated packages for Ubuntu 7.04:\r\n\r\n Source archives:\r\n\r\n

vulnerability in the OpenSSL package included with the Debian GNU/Linux operating system and its derivatives may cause weak cryptographic keys to be generated.\n\n### Description \n\nA weakness exists in the random number generator used by the OpenSSL package included with the Debian GNU/Linux operating system and derivative systems that causes the generated numbers to be predictable. As a result of this weakness, certain encryption keys are much more common than they should be. This vulnerability affects cryptographic applications that use keys generated by the flawed versions of the OpenSSL package. Affected keys include SSH keys, OpenVPN keys, DNSSEC keys, and key material for use in X.509 certificates and session keys used in SSL/TLS connections. Any of these keys generated using the affected systems on or after 2006-09-17 may be vulnerable. Keys generated with GnuPG or GNUTLS on the affected systems are not vulnerable because these applications use their own random number generators and not the one from the flawed version of OpenSSL.\n\nNote that this vulnerability is specific to Debian, Ubuntu Linux and other Debian-derived operating systems. Other systems can be indirectly affected if weak keys generated by the vulnerable systems are imported into them. \n \n--- \n \n### Impact \n\nA remote, unauthenticated attacker with minimal knowledge of the vulnerable system and the ability to conduct a brute force attack against an affected application may be able to guess secret key material. Secondary impacts include authenticated access to the system through the affected service or the ability to perform man-in-the-middle attacks. \n \n--- \n \n### Solution \n\n**Apply a patch from the vendor and regenerate key material** \n \nPatches have been release by the affected vendors. Users are encouraged to review the Systems Affected section of this document and apply the updates it refers to. \n \nDue to the nature of the flaw, any key material generated by the vulnerable versions of the OpenSSL package should be considered fatally defective. Additionally, all DSA keys ever used on affected Debian systems for signing or authentication purposes should be considered compromised since the Digital Signature Algorithm relies on a secret random value used during signature generation. After the software updates are applied, this key material must be regenerated with the updated version of the software. Vendor-specific instructions for doing this can also be found in the Systems Affected section of this document. \n \n--- \n \n### Vendor Information\n\n925211\n\nFilter by status: All Affected Not Affected Unknown\n\nFilter by content: __ Vendor has issued information\n\n__ Sort by: Status Alphabetical\n\nExpand all\n\n__ Affected __ Unknown __ Unaffected \n\n**Javascript is disabled.

Together with my colleagues, we prepared a three-month [practical Information Security course](<https://fintech.tinkoff.ru/tfschool/infsec>): 1 lecture per week with tests and home tasks. \n\nEach lecture is given by a member of our security team, specialized in one of the following modules: **Vulnerability Management**, Application Security, Infrastructure Security, Network Security, Virtualization Security, Banking Systems Security, Blue &amp; Red-teaming, etc.\n\n[](<https://avleonov.com/wp-content/uploads/2019/03/vm_fintech.png>)\n\nThe course is still ongoing, but my Vulnerability Management module is over. Therefore, I want to share my impressions and some statistics.\n\n### Lecture\n\nThe content was pretty much the same as for [my lecture at MIPT ](<https://avleonov.com/2018/12/29/mipt-phystech-guest-lecture-vulnerabilities-money-and-people/>)in December last year. I removed some boring slides about Vulnerability Databases, added some [more critics of Vulnerability Management products](<https://avleonov.com/2018/12/21/guinea-pig-and-vulnerability-management-products/>), their [reports](<https://avleonov.com/2019/01/12/whats-wrong-with-patch-based-vulnerability-management-checks/>) and [detection methods](<https://avleonov.com/2019/02/11/no-left-boundary-for-vulnerability-detection/>). And I also updated information about [open vacancies](<https://avleonov.com/2019/02/04/open-positioner-my-new-project-for-tracking-it-and-security-jobs/>) related to Vulnerability Management.\n\n### Testing\n\nIn the beginning of each lecture, students should solve some tests based on the materials of the previous lecture. Basically it is for motivating them to visit lectures. \n\nI always wondered why Information Security tests are always so weird. They either check the knowledge of some terms or definitions invented by some nonames or the knowledge of reference data, the markings of fire extinguishers in the CISSP exam, for example. Or it is a fascinating game: guess the logic of the individual, who made this question. Anyway, it's far from the real life and the real practice. \n\nWell, I thought so until I had to make my own questions.  It turned out that it's pretty hard to make them unambiguous, reasonable and not based on the subjective experience. As a result, the questions were about Vulnerability Management process, [Vulnerability life cycle](<https://avleonov.com/2019/01/30/vulnerability-life-cycle-and-vulnerability-disclosures/>), [basic vulnerability types](<https://avleonov.com/2018/11/29/making-vulnerable-web-applications-xxs-rce-sql-injection-and-stored-xss-buffer-overflow/>), and Vulnerability Detection issues. All this were in the lecture. Many students answered all the questions correctly, so it seems to me that the test wasn't bad.\n\n### Homework\n\nAnd the most interesting and intriguing part was the homework. There were 2 tasks and the deadline was two weeks. \n\n#### Task 1. Vulnerability Detection and Exploitation\n\n_Deploy virtual machines in your home environment:_\n\n 1. _Vulnerable Target host (for example, Metasploitable or an old version of Windows/Linux)_\n 2. _Vulnerability Scanner (for example, Nessus Home, OpenVAS, Nexpose Community)_\n 3. _Exploitation Tool (for example, Metasploit or some separate exploits)_\n\n_Run vulnerable service on a Vulnerable Target host (for example, SSH), detect vulnerability with Vulnerability Scanner, exploit a vulnerability and get remote access to the host. Make a report how you did it step by step and describe each of your choices. _\n\n_Bonus: write your own detection script for the exploited vulnerability._\n\nIn this task I wanted the students to see \n\n * how the vulnerability could be detected and exploited;\n * that the Vulnerability Scanner is not some magical tool and they can make a small scanner on their own.\n\nThe task was intentionally formulated in a very wide way, without mentioning actual tools and vulnerabilities, because I was curious what exactly would they choose. So, those who are not really interested in the topic could choose something easy, and those who like this stuff could use this task to make an interesting research. \n\nMost of the students chose Metasploitable as a vulnerable target host. Actually, this is the easiest way. But, as you can see, some students chose the usual operating systems: Windows, Ubuntu Linux and docker containers.\n\n\n\nThe same number of students used [Nessus Home](<https://avleonov.com/2016/05/16/tenable-nessus-registration-installation-scanning-reporting/>) and OpenVAS for vulnerability detection. They registered Nessus Home on their own and used it at home environment, so the license agreement was not violated.\n\n\n\nIn most cases students used Metasploit for exploitation. But sometimes it were some custom python scripts or just a curl.\n\n\n\nThey exploited very different vulnerabilities: \n\n\n\n 1. BID:48539 - vsftpd Compromised Source Packages Backdoor Vulnerability \n\n 2. CVE-2004-2687 - DistCC Daemon Command Execution \n 3. CVE-2007-2447 - Samba \"username map script\" Command Execution\n 4. CVE-2008-0166 - Predictable PRNG Brute Force SSH\n 5. CVE-2010-2075 - UnrealIRCD 3.2.8.1 Backdoor Command Execution\n 6. CVE-2015-1427 - Elasticsearch Search Groovy Sandbox Bypass\n 7. **CVE-2017-12617 - Apache Tomcat JSP Upload Bypass / Remote Code Execution**\n 8. CVE-2017-9462 - Mercurial Custom hg-ssh Wrapper Remote Code Exec\n 9. **CVE-2019-0724 - Microsoft Exchange Server Remote Privilege Escalation Vulnerability**\n 10. Distributed Ruby - Distributed Ruby Remote Code Execution\n 11. MS08-067 - Vulnerability in Server Service Could Allow Remote Code Execution\n 12. **MS17-010 - Remote code execution in Microsoft Server Message Block 1.0 (SMBv1) server (EternalBlue)**\n 13. ssh bruteforce - brute-force guess SSH login credentials\n\nI liked the most exploitation of Apache Tomcat RCE (in a docker image), [classical MS17-010](<https://avleonov.com/2017/05/13/wannacry-about-vulnerability-management/>) and new [Microsoft Exchange Server issue](<https://www.tenable.com/blog/proof-of-concept-code-gives-standard-microsoft-exchange-users-domain-administrator-privileges>), because these are the most practical cases. The bruteforce of SSH logins and passwords was not the exploitation that was expected in this task, but why not, this also often happens. \n\nAnd finally the detection scripts. Most of them were unauthenticated and version-based, written in python or bash.\n\n\n\n#### Task 2. Vulnerability Scoring\n\n_Find a new CVE vulnerability without a CVSS vector on _[_nvd.nist.gov_](<https://nvd.nist.gov/>)_ (\"UNDERGOING ANALYSIS\" state) and make CVSS v.3 Base and Temporal Vector for it. Justify your choice. It is advisable to pass the task before the vector will be published on the NVD website._\n\nIn this task I wanted students to see how the criticality of a vulnerability (that Vulnerability Scanner shows) is actually being produced. The vector was not really matter. In fact, it was possible to get Base Vector from the original vulnerability research.  The important part was the justification like \"I chose Attack Vector (AV): Network because\u2026\" just to be seen that this is not a random choice. \n\nAs you can see, very few people take the same vulnerabilities, that is definitely a good sign:\n\n\n\nIt also might be interesting to compare the vector that they've got as a result of this task with the vector from the NVD. Most likely there will the differences because CVSS is pretty subjective. \n\n### In conclusion\n\nThis was my second time when I gave a lecture and the first time I made additional educational content: tests and homework. It was very cool and exciting. I hope the students have their fun too. \n\nThis was only the first module, there is still a lot of content and interesting practical tasks from my colleagues. I hope that all the students will successfully go through all the stages and with some of them we will meet at work or on internship.\n\n", "modified": "2019-03-04T10:38:31", "published": "2019-03-04T10:38:31", "id": "AVLEONOV:54F79F8B5C71E738DB16AEA2DF8FFD2F", "href": "http://feedproxy.google.com/~r/avleonov/~3/VfGsxXaJTBs/", "type": "avleonov", "title": "Vulnerability Management at Tinkoff Fintech School", "cvss": {"score": 9.3, "vector": "AV:N/AC:M/Au:N/C:C/I:C/A:C"}}]}
