Ubuntu: KTorrent vulnerabilities  26 January 2009 
Posted by Benjamin D. Thomas

Ubuntu: xine-lib vulnerabilities  26 January 2009 
Posted by Benjamin D. Thomas   
It was discovered that xine-lib did not correctly handle certain malformed Ogg and Windows Media files. If a user or automated system were tricked into opening a specially crafted Ogg or Windows Media file, an attacker could cause xine-lib to crash, creating a denial of service. This issue only applied to Ubuntu 6.06 LTS, 7.10, and 8.04 LTS. (CVE-2008-3231)...
 
Ubuntu:Perl regression  15 January 2009 
Posted by Benjamin D. Thomas   
USN-700-1 fixed vulnerabilities in Perl. Due to problems with the Ubuntu 8.04 build, some Perl .ph files were missing from the resulting update. This update fixes the problem. We apologize for the inconvenience.
 
Ubuntu: HPLIP vulnerability  13 January 2009 
Posted by Benjamin D. Thomas   
It was discovered that an installation script in the HPLIP package would change permissions on the hplip config files located in user's home directories. A local user could exploit this and change permissions on arbitrary files upon an HPLIP installation or upgrade, which could lead to root privileges.
 
Ubuntu: CUPS vulnerabilities  12 January 2009 
Posted by Benjamin D. Thomas   
It was discovered that CUPS didn't properly handle adding a large number of RSS subscriptions. A local user could exploit this and cause CUPS to crash, leading to a denial of service. This issue only applied to Ubuntu 7.10, 8.04 LTS and 8.10. (CVE-2008-5183) It was discovered that CUPS did not authenticate users when adding and cancelling RSS subscriptions. An unprivileged local user could bypass intended restrictions and add a large number of RSS subscriptions. This issue only applied to Ubuntu 7.10 and 8.04 LTS. (CVE-2008-5184) It was discovered that the PNG filter in CUPS did not properly handle certain malformed images. If a user or automated system were tricked into opening a crafted PNG image file, a remote attacker could cause a denial of service or execute arbitrary code with user privileges. In Ubuntu 7.10, 8.04 LTS, and 8.10, attackers would be isolated by the AppArmor CUPS profile. (CVE-2008-5286) It was discovered that the example pstopdf CUPS filter created log files in an insecure way. Local users could exploit a race condition to create or overwrite files with the privileges of the user invoking the program. This issue only applied to Ubuntu 6.06 LTS, 7.10, and 8.04 LTS. (CVE-2008-5377)
 
Ubuntu: Samba vulnerability  05 January 2009 
Posted by Benjamin D. Thomas   
Gunter Höckel discovered that Samba with registry shares enabled did not properly validate share names. An authenticated user could gain access to the root filesystem by using an older version of smbclient and specifying an empty string as a share name. This is only an issue if registry shares are enabled on the server by setting "registry shares = yes", "include = registry", or "config backend = registry", which is not the default.

Original advisory details: Multiple memory overflow flaws were discovered in OpenOffice.org's handling of WMF and EMF files. If a user were tricked into opening a specially crafted document, a remote attacker might be able to execute arbitrary code with user privileges. (CVE-2008-2237, CVE-2008-2238)
