Ubuntu: KDE vulnerability  06 May 2008 
Posted by Benjamin D. Thomas   
It was discovered that start_kdeinit in KDE 3 did not properly sanitize its input. A local attacker could exploit this to send signals to other processes and cause a denial of service or possibly execute arbitrary code. (CVE-2008-1671)
 
Ubuntu: Emacs vulnerabilities  06 May 2008 
Posted by Benjamin D. Thomas   
It was discovered that Emacs did not account for precision when formatting integers. If a user were tricked into opening a specially crafted file, an attacker could cause a denial of service or possibly other unspecified actions. This issue does not affect Ubuntu 8.04. (CVE-2007-6109) Steve Grubb discovered that the vcdiff script as included in Emacs created temporary files in an insecure way when used with SCCS. Local users could exploit a race condition to create or overwrite files with the privileges of the user invoking the program. (CVE-2008-1694)
 
Ubuntu: CUPS vulnerability  05 May 2008 
Posted by Benjamin D. Thomas   
Thomas Pollet discovered that CUPS did not properly validate the size of PNG images. A local attacker, and a remote attacker if printer sharing is enabled, could send a crafted file and cause a denial of service or possibly execute arbitrary code as the non-root user in Ubuntu 6.06 LTS and 7.04. In Ubuntu 7.10, attackers would be isolated by the AppArmor CUPS profile. (CVE-2008-1722)
 
Ubuntu: Firefox vulnerabilities  22 April 2008 
Posted by Benjamin D. Thomas   
Flaws were discovered in Firefox which could lead to crashes during JavaScript garbage collection. If a user were tricked into opening a malicious web page, an attacker may be able to crash the browser or possibly execute arbitrary code with the user's privileges. (CVE-2008-1380)
 
Ubuntu: Gnumeric vulnerability  21 April 2008 
Posted by Benjamin D. Thomas   
Thilo Pfennig and Morten Welinder discovered that the XLS spreadsheet handling code in Gnumeric did not correctly calculate needed memory sizes.

Posted by Benjamin D. Thomas   
It was discovered that the poppler PDF library did not correctly handle certain malformed embedded fonts. If a user or an automated system were tricked into opening a malicious PDF, a remote attacker could execute arbitrary code with user privileges.
