Ubuntu: Avahi vulnerability  10 November 2006 
Posted by Benjamin D. Thomas   
Steve Grubb discovered that netlink messages were not being checked for their sender identity. This could lead to local users manipulating the Avahi service.
Ubuntu: texinfo vulnerability  09 November 2006 
Posted by Benjamin D. Thomas   
Miloslav Trmac discovered a buffer overflow in texinfo's index processor. If a user is tricked into processing a .texi file with texindex, this could lead to arbitrary code execution with user privileges.
Ubuntu: imlib2 regression fix  06 November 2006 
Posted by Benjamin D. Thomas   
USN-376-1 provided an update to imlib2 to fix several security vulnerabilities. Unfortunately the update broke JPG file handling in certain situations. This update corrects this problem. We apologize for the inconvenience.
Ubuntu: RPM vulnerability  03 November 2006 
Posted by Benjamin D. Thomas   
An error was found in the RPM library's handling of query reports. In some locales, certain RPM packages would cause the library to crash. If a user was tricked into querying a specially crafted RPM package, the flaw could be exploited to execute arbitrary code with the user's privileges.
Ubuntu: NVIDIA vulnerability  03 November 2006 
Posted by Benjamin D. Thomas   
Derek Abdine discovered that the NVIDIA Xorg driver did not correctly verify the size of buffers used to render text glyphs. When displaying very long strings of text, the Xorg server would crash. If a user were tricked into viewing a specially crafted series of glyphs, this flaw could be exploited to run arbitrary code with root privileges.
Ubuntu: imlib2 vulnerabilities  03 November 2006 
Posted by Benjamin D. Thomas   
M. Joonas Pihlaja discovered that imlib2 did not sufficiently verify the validity of ARGB, JPG, LBM, PNG, PNM, TGA, and TIFF images. If a user were tricked into viewing or processing a specially crafted image with an application that uses imlib2, the flaws could be exploited to execute arbitrary code with the user's privileges.
Ubuntu: PHP vulnerability  02 November 2006 
Posted by Benjamin D. Thomas   
Stefan Esser discovered two buffer overflows in the htmlentities() and htmlspecialchars() functions. By supplying specially crafted input to PHP applications which process that input with these functions, a remote attacker could potentially exploit this to execute arbitrary code with the privileges of the application. (CVE-2006-5465) This update also fixes bugs in the chdir() and tempnam() functions, which did not perform proper open_basedir checks. This could allow local scripts to bypass intended restrictions.
