M. Joonas Pihlaja discovered that ImageMagick did not sufficiently verify the validity of PALM and DCM images. When processing a specially crafted image with an application that uses imagemagick, this could be exploited to execute arbitrary code with the application's privileges.
USN-369-1 fixed three minor PostgreSQL 8.1 vulnerabilities for Ubuntu 6.06 LTS. This update provides the corresponding update for Ubuntu 6.10.
An SQL injection was discovered in Pike's PostgreSQL module. Applications using a PostgreSQL database and uncommon character encodings could be fooled into running arbitrary SQL commands, which could result in privilege escalation within the application, application data exposure, or denial of service.
A buffer overflow was discovered in gas (the GNU assembler). By tricking an user or automated system (like a compile farm) into assembling a specially crafted source file with gcc or gas, this could be exploited to execute arbitrary code with the user's privileges.
A parsing failure was discovered in the handling of X.509 certificates that contained extra trailing data. Malformed or malicious certificates could cause services using libksba to crash, potentially creating a denial of service.
A race condition existed that would allow other local users to see error messages generated during another user's X session. This could allow potentially sensitive information to be leaked.
USN-346-1 provided an updated Linux kernel to fix several security vulnerabilities. Unfortunately the update broke the binary 'nvidia' driver from linux-restricted-modules. This update corrects this problem. We apologize for the inconvenience.
There are multiple vulnerabilities in MySQL. The following CVEIDs have been addressed: CVE-2006-4227 CVE-2006-4031
Philip Mackenzie, Marius Schilder, Jason Waddle and Ben Laurie of Google Security discovered that the OpenSSL library did not sufficiently check the padding of PKCS #1 v1.5 signatures if the exponent of the public key is 3 (which is widely used for CAs). This could be exploited to forge signatures without the need of the secret key.
An integer overflow has been discovered in X.org's font handling library. By using a specially crafted font file, this could be exploited to crash the X server or execute arbitrary code with root privileges.
bind did not sufficiently verify particular requests and responses from other name servers and users. By sending a specially crafted packet, a remote attacker could exploit this to crash the name server.
Sridhar Samudrala discovered a local Denial of Service vulnerability in the handling of SCTP sockets. By opening such a socket with a special SO_LINGER value, a local attacker could exploit this to crash the kernel. (CVE-2006-4535) Kirill Korotaev discovered that the ELF loader on the ia64 and sparc platforms did not sufficiently verify the memory layout. By attempting to execute a specially crafted executable, a local user could exploit this to crash the kernel. (CVE-2006-4538)
XFOCUS Security Team discovered that the AVI decoder used in xine-lib did not correctly validate certain headers. By tricking a user into playing an AVI with malicious headers, an attacker could execute arbitrary code with the target user's privileges. (CVE-2006-4799) Multiple integer overflows were discovered in ffmpeg and tools that contain a copy of ffmpeg (like xine-lib and kino), for several types of video formats. By tricking a user into running a video player that uses ffmpeg on a stream with malicious content, an attacker could execute arbitrary code with the target user's privileges. (CVE-2006-4800)
Steve Alexander discovered that mailman did not properly handle attachments with special filenames. A remote user could exploit that to stop mail delivery until the server administrator manually cleaned these posts. (CVE-2006-2941) Various cross-site scripting vulnerabilities have been reported by Barry Warsaw. By using specially crafted email addresses, names, and similar arbitrary user-defined strings, a remote attacker could exploit this to run web script code in the list administrator's web browser. (CVE-2006-3636) URLs logged to the error log file are now checked for invalid characters. Before, specially crafted URLs could inject arbitrary messages into the log.
The GnuTLS library did not sufficiently check the padding of PKCS #1 v1.5 signatures if the exponent of the public key is 3 (which is widely used for CAs). This could be exploited to forge signatures without the need of the secret key.
Tavis Ormandy discovered that gzip did not sufficiently verify the validity of gzip or compress archives while unpacking. By tricking an user or automated system into unpacking a specially crafted compressed file, this could be exploited to execute arbitrary code with the user's privileges.
Benjamin C. Wiley Sittler discovered that Python's repr() function did not properly handle UTF-32/UCS-4 strings. If an application uses repr() on arbitrary untrusted data, this could be exploited to execute arbitrary code with the privileges of the python application.
Various flaws have been reported that allow an attacker to execute arbitrary code with user privileges by tricking the user into opening a malicious web page containing JavaScript. The following CVEIDs have been addressed: CVE-2006-4253, CVE-2006-4565, CVE-2006-4566, CVE-2006-4568, CVE-2006-4569, CVE-2006-4571, CVE-2006-4340, CVE-2006-4567
Various flaws have been reported that allow an attacker to execute arbitrary code with user privileges by tricking the user into opening a malicious email containing JavaScript. Please note that JavaScript is disabled by default for emails, and it is not recommended to enable it. The following CVEIDs have been addressed: CVE-2006-4253, CVE-2006-4565, CVE-2006-4566, CVE-2006-4571, CVE-2006-4340, CVE-2006-4567, CVE-2006-4570
Will Drewry, of the Google Security Team, discovered buffer overflows in GDB's DWARF processing. This would allow an attacker to execute arbitrary code with user privileges by tricking the user into using GDB to load an executable that contained malicious debugging information.
