Amazon Linux AMI : nss (ALAS-2012-108)

A flaw was found in the way the ASN.1 Abstract Syntax Notation One decoder in NSS handled zero length items. This flaw could cause the decoder to incorrectly skip or replace certain items with a default value, or could cause an application to crash if, for example, it received a specially crafted...

Amazon Linux AMI : libxslt (ALAS-2012-123)

A heap-based buffer overflow flaw was found in the way libxslt applied templates to nodes selected by certain namespaces. An attacker could use this flaw to create a malicious XSL file that, when used by an application linked against libxslt to perform an XSL transformation, could cause the...

Amazon Linux AMI : libxml2 (ALAS-2012-143)

A heap-based buffer underflow flaw was found in the way libxml2 decoded certain entities. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the...

Amazon Linux AMI : freetype (ALAS-2013-150)

A flaw was found in the way the FreeType font rendering engine processed certain Glyph Bitmap Distribution Format BDF fonts. If a user loaded a specially crafted font file with an application linked against FreeType, it could cause the application to crash or, possibly, execute arbitrary code wit...

Amazon Linux AMI : kernel (ALAS-2012-58)

The ExecShield feature does not properly handle use of many shared libraries by a 32-bit executable file, which makes it easier for context-dependent attackers to bypass the ASLR protection mechanism by leveraging a predictable base address for one of these libraries. C Tenable Network Security,...

Fedora 18 : lighttpd-1.4.32-1.fc18 (2013-15344)

One important denial of service in 1.4.31 fix: CVE-2012-5533. A flaw was found in lighttpd version 1.4.31 that could be exploited by a remote user to cause a denial of service condition in lighttpd. A client could send a malformed Connection header to lighttpd such as 'Connection: TE,,Keep-Alive'...

Amazon Linux AMI : glibc (ALAS-2012-120)

Multiple integer overflow flaws, leading to stack-based buffer overflows, were found in glibc's functions for converting a string to a numeric representation strtod, strtof, and strtold. If an application used such a function on attacker controlled input, it could cause the application to crash o...

Amazon Linux AMI : httpd (ALAS-2012-46)

It was discovered that the fix for CVE-2011-3368 did not completely address the problem. An attacker could bypass the fix and make a reverse proxy connect to an arbitrary server not directly accessible to the attacker by sending an HTTP version 0.9 request, or by using a specially crafted URI...

Amazon Linux AMI : libxml2 (ALAS-2012-134)

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the way libxml2 handled documents that enable entity expansion. A remote attacker could provide a large, specially crafted XML file that, when opened in an application linked against libxml2, would cause the...

Amazon Linux AMI : python-crypto (ALAS-2012-86)

PyCrypto before 2.6 does not produce appropriate prime numbers when using an ElGamal scheme to generate a key, which reduces the signature space or public key space and makes it easier for attackers to conduct brute-force attacks to obtain the private key. C Tenable Network Security, Inc. The...

Amazon Linux AMI : libtiff (ALAS-2012-147)

A heap-based buffer overflow flaw was found in the way libtiff processed certain TIFF images using the Pixar Log Format encoding. An attacker could create a specially crafted TIFF file that, when opened, could cause an application using libtiff to crash or, possibly, execute arbitrary code with t...

Amazon Linux AMI : kernel (ALAS-2012-83)

It was found that the datalen parameter of the sockallocsendpskb function in the Linux kernel's networking implementation was not validated before use. A local user with access to a TUN/TAP virtual interface could use this flaw to crash the system or, potentially, escalate their privileges. Note...

Amazon Linux AMI : jakarta-commons-httpclient (ALAS-2013-169)

The Jakarta Commons HttpClient component did not verify that the server hostname matched the domain name in the subject's Common Name CN or subjectAltName field in X.509 certificates. This could allow a man-in-the-middle attacker to spoof an SSL server if they had a certificate that was valid for...

Amazon Linux AMI : openjpeg (ALAS-2012-111)

An input validation flaw, leading to a heap-based buffer overflow, was found in the way OpenJPEG handled the tile number and size in an image tile header. A remote attacker could provide a specially crafted image file that, when decoded using an application linked against OpenJPEG, would cause th...

Amazon Linux AMI : libxml2 (ALAS-2012-52)

It was found that the hashing routine used by libxml2 arrays was susceptible to predictable hash collisions. Sending a specially crafted message to an XML service could result in longer processing time, which could lead to a denial of service. To mitigate this issue, randomization has been added ...

Amazon Linux AMI : php (ALAS-2012-116)

Unspecified vulnerability in the phpstreamscandir function in the stream implementation in PHP before 5.3.15 and 5.4.x before 5.4.5 has unknown impact and remote attack vectors, related to an 'overflow.' C Tenable Network Security, Inc. The descriptive text and package checks in this plugin were...

Amazon Linux AMI : libtiff (ALAS-2012-106)

libtiff did not properly convert between signed and unsigned integer values, leading to a buffer overflow. An attacker could use this flaw to create a specially crafted TIFF file that, when opened, would cause an application linked against libtiff to crash or, possibly, execute arbitrary code...

Amazon Linux AMI : systemtap (ALAS-2012-54)

An invalid pointer read flaw was found in the way SystemTap handled malformed debugging information in DWARF format. When SystemTap unprivileged mode was enabled, an unprivileged user in the stapusr group could use this flaw to crash the system or, potentially, read arbitrary kernel memory...
