Ubuntu: PostgreSQL vulnerabilities  05 February 2007 
Posted by Benjamin D. Thomas   
Jeff Trout discovered that the PostgreSQL server did not sufficiently check data types of SQL function arguments in some cases. An authenticated attacker could exploit this to crash the database server or read out arbitrary locations in the server's memory, which could allow retrieving database content the attacker should not be able to see. (CVE-2007-0555)
 
Ubuntu: GTK vulnerability  01 February 2007 
Posted by Benjamin D. Thomas   
A flaw was discovered in the error handling of GTK's image loading library. Applications opening certain corrupted images could be made to crash, causing a denial of service.
 
Ubuntu: Firefox regression  26 January 2007 
Posted by Benjamin D. Thomas   
USN-398-2 fixed vulnerabilities in Firefox 1.5. However, when auto-filling saved-password login forms without a username field, Firefox would crash. This update fixes the problem. We apologize for the inconvenience.
 
Ubuntu: teTeX vulnerability  25 January 2007 
Posted by Benjamin D. Thomas   
USN-410-1 fixed vulnerabilities in the poppler PDF loader library. This update provides the corresponding updates for a copy of this code in tetex-bin in Ubuntu 5.10. Versions of tetex-bin after Ubuntu 5.10 use poppler directly and do not need a separate update.
 
Ubuntu: Squid vulnerabilities  24 January 2007 
Posted by Benjamin D. Thomas   
David Duncan Ross Palmer and Henrik Nordstrom discovered that squid incorrectly handled special characters in FTP URLs. Remote users with access to squid could crash the server leading to a denial of service.
 
Ubuntu: BlueZ vulnerability  23 January 2007 
Posted by Benjamin D. Thomas   
A flaw was discovered in the HID daemon of bluez-utils. A remote attacker could gain control of the mouse and keyboard if hidd was enabled. This does not affect a default Ubuntu installation, since hidd is normally disabled.
 
Ubuntu: GeoIP vulnerability  23 January 2007 
Posted by Benjamin D. Thomas   
Dean Gaudet discovered that the GeoIP update tool did not validate the filename responses from the update server. A malicious server, or man-in-the-middle system posing as a server, could write to arbitrary files with user privileges.
