John Heasman discovered that OpenOffice did not correctly validate the sizes of tags in RTF documents. If a user were tricked into opening a specially crafted document, a remote attacker could execute arbitrary code with user privileges.
Multiple vulnerabilities were found in ImageMagick's handling of DCM and WXD image files. By tricking a user into processing a specially crafted image with an application that uses imagemagick, an attacker could execute arbitrary code with the user's privileges.
Stefan Cornelius discovered that Gimp could miscalculate the size of heap buffers when processing PSD images. By tricking a user into opening a specially crafted PSD file with Gimp, an attacker could exploit this to execute arbitrary code with the user's privileges.
Philip Van Hoof discovered that the IMAP client in Evolution did not correctly verify the SEQUENCE value. A malicious or spoofed server could exploit this to execute arbitrary code with user privileges.
Wei Wang discovered that the krb5 RPC library did not correctly handle certain error conditions. A remote attacker could cause kadmind to free an uninitialized pointer, leading to a denial of service or possibly execution of arbitrary code with root privileges.
Multiple flaws in the MadWifi driver were discovered that could lead to a system crash. A physically near-by attacker could generate specially crafted wireless network traffic and cause a denial of service.
Fabio Massimo Di Nitto discovered that cman did not correctly validate the size of client messages. A local user could send a specially crafted message and execute arbitrary code with cluster manager privileges or crash the manager, leading to a denial of service.
Sean Larsson discovered that libexif did not correctly verify the size of EXIF components. By tricking a user into opening an image with specially crafted EXIF headers, a remote attacker could cause the application using libexif to execute arbitrary code with user privileges.
It was discovered that xscreensaver did not correctly validate the return values from network authentication systems such as LDAP or NIS. A local attacker could bypass a locked screen if they were able to interrupt network connectivity.
A buffer overflow was discovered in libgd2's font renderer. By tricking an application using libgd2 into rendering a specially crafted string with a JIS encoded font, a remote attacker could read heap memory or crash the application, leading to a denial of service. (CVE-2007-0455) Xavier Roche discovered that libgd2 did not correctly validate PNG callback results. If an application were tricked into processing a specially crafted PNG image, it would monopolize CPU resources.
USN-439-1 fixed a vulnerability in file. The original fix did not fully solve the problem. This update provides a more complete solution. Jean-Sebastien Guay-Leroux discovered that "file" did not correctly check the size of allocated heap memory. If a user were tricked into examining a specially crafted file with the "file" utility, a remote attacker could execute arbitrary code with user privileges.
Victor Stinner discovered that libexif did not correctly validate the size of some EXIF header fields. By tricking a user into opening an image with specially crafted EXIF headers, a remote attacker could cause the application using libexif to crash, resulting in a denial of service.
USN-464-1 fixed several vulnerabilities in the Linux kernel. Some additional code changes were accidentally included in the Feisty update which caused trouble for some people who were not using UUID-based filesystem mounts. These changes have been reverted. We apologize for the inconvenience. For more information see: https://launchpad.net/bugs/117314 https://wiki.ubuntu.com/UsingUUID
It was discovered that Gimp did not correctly handle RAS image format color tables. By tricking a user into opening a specially crafted RAS file with Gimp, an attacker could exploit this to execute arbitrary code with the user's privileges.
Victor Stinner discovered that freetype did not correctly verify the number of points in a TrueType font. If a user were tricked into using a specially crafted font, a remote attacker could execute arbitrary code with user privileges.
Luigi Auriemma discovered multiple flaws in pulseaudio's network processing code. If an unauthenticated attacker sent specially crafted requests to the pulseaudio daemon, it would crash, resulting in a denial of service.
Philipp Richter discovered that the AppleTalk protocol handler did not sufficiently verify the length of packets. By sending a crafted AppleTalk packet, a remote attacker could exploit this to crash the kernel.
Tomas Golembiovsky discovered that some vim commands were accidentally allowed in modelines. By tricking a user into opening a specially crafted file in vim, an attacker could execute arbitrary code with user privileges.
A flaw was discovered in the FTP command handler in PHP. Commands were not correctly filtered for control characters. An attacker could issue arbitrary FTP commands using specially crafted arguments.
