Ubuntu: Ekiga vulnerabilities  22 February 2007 
Posted by Benjamin D. Thomas   
Mu Security discovered a format string vulnerability in Ekiga. If a user was running Ekiga and listening for incoming calls, a remote attacker could send a crafted call request, and execute arbitrary code with the user's privileges.
Ubuntu: slocate vulnerability  21 February 2007 
Posted by Benjamin D. Thomas   
A flaw was discovered in the permission checking code of slocate. When reporting matching files, locate would not correctly respect the parent directory's "read" bits. This could result in filenames being displayed when the file owner had expected them to remain hidden from other system users.
Ubuntu: PHP vulnerabilities  21 February 2007 
Posted by Benjamin D. Thomas   
Multiple buffer overflows have been discovered in various PHP modules. If a PHP application processes untrusted data with functions of the session or zip module, or various string functions, a remote attacker could exploit this to execute arbitrary code with the privileges of the web server.
Ubuntu: MoinMoin vulnerabilities  20 February 2007 
Posted by Benjamin D. Thomas   
A flaw was discovered in MoinMoin's debug reporting sanitizer which could lead to a cross-site scripting attack. By tricking a user into viewing a crafted MoinMoin URL, an attacker could execute arbitrary JavaScript as the current MoinMoin user, possibly exposing the user's authentication information for the domain where MoinMoin was hosted.
Ubuntu: ImageMagick vulnerabilities  15 February 2007 
Posted by Benjamin D. Thomas   
Vladimir Nadvornik discovered that the fix for CVE-2006-5456, released in USN-372-1, did not correctly solve the original flaw in PALM image handling. 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.
Ubuntu: PostgreSQL regression  12 February 2007 
Posted by Benjamin D. Thomas   
USN-417-2 fixed a severe regression in the PostgreSQL server that was introduced in USN-417-1 and caused some valid queries to be aborted with a type error. This update fixes a similar (but much less prominent) error. At the same time, PostgreSQL is updated to version 8.1.8, which fixes a range of important bugs.
Ubuntu: Linux kernel vulnerabilities  10 February 2007 
Posted by Benjamin D. Thomas   
Mark Dowd discovered that the netfilter iptables module did not correcly handle fragmented IPv6 packets.
