Ubuntu 4.10 / 5.04 : apache2, libapache-mod-ssl vulnerabilities (USN-177-1)

Apache did not honour the 'SSLVerifyClient require' directive within a block if the surrounding block contained a directive 'SSLVerifyClient optional'. This allowed clients to bypass client certificate validation on servers with the above configuration. CAN-2005-2700 Filip Sneppe discovered a...

Ubuntu 4.10 : imlib2 vulnerabilities (USN-55-1)

Recently, Pavel Kankovsky discovered several buffer overflows in imlib which were fixed in USN-53-1. It was found that imlib2 was vulnerable to similar issues. If an attacker tricked a user into loading a malicious XPM or BMP image, he could exploit this to execute arbitrary code in the context o...

Ubuntu 4.10 : libdbi-perl vulnerabilities (USN-70-1)

Javier Fernandez-Sanguino Pena from the Debian Security Audit Project discovered that the module DBI::ProxyServer in Perl's DBI library created a PID file in an insecure manner. This could allow a symbolic link attack to create or overwrite arbitrary files with the privileges of the user invoking...

Ubuntu 4.10 : krb5 vulnerability (USN-58-1)

Michael Tautschnig discovered a possible buffer overflow in the addtohistory function in the MIT Kerberos 5 implementation. Performing a password change did not properly track the password policy's history count and the maximum number of keys. This could cause an array overflow and may have allow...

Ubuntu 4.10 : evolution vulnerability (USN-69-1)

Max Vozeler discovered an integer overflow in camel-lock-helper. An user-supplied length value was not validated, so that a value of -1 caused a buffer allocation of 0 bytes; this buffer was then filled by an arbitrary amount of user-supplied data. A local attacker or a malicious POP3 server coul...

Ubuntu 4.10 / 5.04 : openldap2, libpam-ldap, libnss-ldap vulnerabilities (USN-152-1)

Andrea Barisani discovered a flaw in the SSL handling of pam-ldap and libnss-ldap. When a client connected to a slave LDAP server using SSL, the slave server did not use SSL as well when contacting the LDAP master server. This caused passwords and other confident information to be transmitted...

Fedora Core 3 : mod_auth_pgsql-2.0.1-6.2 (2006-014)

Several format string flaws were found in the way modauthpgsql logs information. It may be possible for a remote attacker to execute arbitrary code as the 'apache' user if modauthpgsql is used for user authentication. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-365...

Ubuntu 4.10 : tiff vulnerability (USN-54-1)

Dmitry V. Levin discovered a buffer overflow in the 'tiffdump' utility. If an attacker tricked a user into processing a malicious TIFF image with tiffdump, they could cause a buffer overflow which at least causes the program to crash. However, it is not entirely clear whether this can be exploite...

Ubuntu 4.10 : openssh information leakage (USN-34-1)

@Mediaservice.net discovered two information leaks in the OpenSSH server. When using password authentication, an attacker could test whether a login name exists by measuring the time between failed login attempts, i. e. the time after which the 'password:' prompt appears again. A similar issue...

Ubuntu 4.10 / 5.04 / 5.10 : libungif4 vulnerabilities (USN-214-1)

Chris Evans discovered several buffer overflows in the libungif library. By tricking an user or automated system into processing a specially crafted GIF image, this could be exploited to execute arbitrary code with the privileges of the application using libungif. Note that Tenable Network Securi...

Ubuntu 4.10 / 5.04 : net-snmp vulnerability (USN-190-1)

A remote Denial of Service has been discovered in the SMNP Simple Network Management Protocol library. If a SNMP agent uses TCP sockets for communication, a malicious SNMP server could exploit this to crash the agent. Please note that by default SNMP uses UDP sockets. Note that Tenable Network...

Ubuntu 4.10 : reportbug information disclosure (USN-88-1)

Rolf Leggewie discovered two information disclosure bugs in reportbug. The per-user configuration file /.reportbugrc was created world-readable. If it contained email smarthost passwords, these were readable by any other user on the computer storing the home directory. reportbug usually includes...

Ubuntu 4.10 : php4 vulnerability (USN-66-2)

Ubuntu Security Notice USN-66-1 described a circumvention of the 'openbasedir' restriction by using the cURL module. Adam Conrad discovered that the fix from USN-66-1 still allowed to bypass this restriction with certain variants of path specifications. In addition this update fixes the crash of...

Ubuntu 4.10 : imagemagick vulnerability (USN-90-1)

Tavis Ormandy discovered a format string vulnerability in ImageMagick's file name handling. Specially crafted file names could cause a program using ImageMagick to crash, or possibly even cause execution of arbitrary code. Since ImageMagick can be used in custom printing systems, this also might...

Ubuntu 4.10 : cdrtools vulnerability (USN-100-1)

Javier Fernandez-Sanguino Pena noticed that cdrecord created temporary files in an insecure manner if DEBUG was enabled in /etc/cdrecord/rscsi. If the default value was used which stored the debug output file in /tmp, this could allow a symbolic link attack to create or overwrite arbitrary files...

Ubuntu 4.10 : ntp vulnerability (USN-175-1)

Thomas Biege discovered a flaw in the privilege dropping of the NTP server. When ntpd was configured to drop root privileges, and the group to run under was specified as a name as opposed to a numeric group ID, ntpd changed to the wrong group. Depending on the actual group it changed to, this cou...

Ubuntu 4.10 / 5.04 : bzip2 vulnerabilities (USN-127-1)

Imran Ghory discovered a race condition in the file permission restore code of bunzip2. While a user was decompressing a file, a local attacker with write permissions in the directory of that file could replace the target file with a hard link. This would cause bzip2 to restore the file permissio...

Ubuntu 4.10 / 5.04 : gzip vulnerability (USN-158-1)

zgrep did not handle shell metacharacters like '|' and '&' properly when they occurred in input file names. This could be exploited to execute arbitrary commands with user privileges if zgrep is run in an untrusted directory with specially crafted file names. Note that Tenable Network Security ha...
