Amazon Linux AMI : nss (ALAS-2014-385)

Use-after-free vulnerability in the CERTDestroyCertificate function in libnss3.so in Mozilla Network Security Services NSS 3.x, as used in Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7, allows remote attackers to execute arbitrary code via vectors that trigger...

Amazon Linux AMI : mod24_wsgi (ALAS-2014-375)

It was found that modwsgi did not properly drop privileges if the call to setuid failed. If modwsgi was set up to allow unprivileged users to run WSGI applications, a local user able to run a WSGI application could possibly use this flaw to escalate their privileges on the system. Note: modwsgi i...

Amazon Linux AMI : kernel (ALAS-2014-417)

fs/namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNTNODEV, MNTNOSUID, and MNTNOEXEC and changing MNTATIMEMASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had atime enabled, ...

Amazon Linux AMI : openssl097a (ALAS-2014-351)

It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server. CVE-2014-0224 C Tenable Network...

Amazon Linux AMI : chrony (ALAS-2014-366)

It was reported that the cmdmon protocol implemented in chrony was found to be vulnerable to DDoS attacks using traffic amplification. By default, commands are allowed only from localhost, but it's possible to configure chronyd to allow commands from any address. This could allow a remote attacke...

Amazon Linux AMI : squid (ALAS-2014-360)

A denial of service flaw was found in the way Squid processed certain HTTPS requests when the SSL Bump feature was enabled. A remote attacker could send specially crafted requests that could cause Squid to crash. CVE-2014-0128 C Tenable Network Security, Inc. The descriptive text and package chec...

Amazon Linux AMI : tomcat6 (ALAS-2014-344)

It was found that when Tomcat processed a series of HTTP requests in which at least one request contained either multiple content-length headers, or one content-length header with a chunked transfer-encoding header, Tomcat would incorrectly handle the request. A remote attacker could use this fla...

Amazon Linux AMI : glibc (ALAS-2014-399)

An off-by-one heap-based buffer overflow flaw was found in glibc's internal gconvtranslitfind function. An attacker able to make an application call the iconvopen function with a specially crafted argument could possibly use this flaw to execute arbitrary code with the privileges of that...

Amazon Linux AMI : perl-Capture-Tiny (ALAS-2014-358)

"It was found 1 that the Capture::Tiny module, provided by the perl-Capture-Tiny package, used the File::temp::tmpnam module to generate temporary files : ./lib/Capture/Tiny.pm: $stash-flagfiles$which = scalar tmpnam C Tenable Network Security, Inc. The descriptive text and package checks in this...

Amazon Linux AMI : php54 (ALAS-2014-343)

The BEGIN regular expression in the awk script detector in magic/Magdir/commands in file before 5.15 uses multiple wildcards with unlimited repetitions, which allows context-dependent attackers to cause a denial of service CPU consumption via a crafted ASCII file that triggers a large amount of...

Amazon Linux AMI : jbigkit (ALAS-2014-337)

Stack-based buffer overflow in the jbgdecin function in libjbig/jbig.c in JBIG-KIT before 2.1 allows remote attackers to cause a denial of service application crash and possibly execute arbitrary code via a crafted image file. C Tenable Network Security, Inc. The descriptive text and package chec...

Amazon Linux AMI : glibc (ALAS-2014-355)

Multiple stack-based buffer overflows in net/netfilter/ipvs/ipvsctl.c in the Linux kernel before 2.6.33, when CONFIGIPVS is used, allow local users to gain privileges by leveraging the CAPNETADMIN capability for 1 a getsockopt system call, related to the doipvsgetctl function, or 2 a setsockopt...

Amazon Linux AMI : transmission (ALAS-2014-390)

Integer overflow in the trbitfieldEnsureNthBitAlloced function in bitfield.c in Transmission before 2.84 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted peer message, which triggers an out-of-bounds write. C Tenable Network Security, Inc. The...

Amazon Linux AMI : nss (ALAS-2014-424)

A flaw was found in the way NSS parsed ASN.1 Abstract Syntax Notation One input from certain RSA signatures.
