Ubuntu: freetype vulnerability  30 May 2007 
Posted by Benjamin D. Thomas

Ubuntu: PulseAudio vulnerability  25 May 2007 
Posted by Benjamin D. Thomas   
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.
Ubuntu: Linux kernel vulnerabilities  24 May 2007 
Posted by Benjamin D. Thomas

Ubuntu: vim vulnerability  22 May 2007 
Posted by Benjamin D. Thomas   
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.
Ubuntu: PHP vulnerabilities  22 May 2007 
Posted by Benjamin D. Thomas

Ubuntu: Samba regression  22 May 2007 
Posted by Benjamin D. Thomas   
USN-460-1 fixed several vulnerabilities in Samba. The upstream changes for CVE-2007-2444 had an unexpected side-effect in Feisty. Paul Griffith and Andrew Hogue discovered that Samba did not fully drop root privileges while translating SIDs. A remote authenticated user could issue SMB operations during a small window of opportunity and gain root privileges. (CVE-2007-2444)
Ubuntu: pptpd regression  21 May 2007 
Posted by Benjamin D. Thomas   
USN-459-1 fixed vulnerabilities in pptpd. However, a portion of the fix caused a regression in session establishment under Dapper for certain PPTP clients. This update fixes the problem. We apologize for the inconvenience.
