Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : cups, cupsys vulnerabilities (USN-952-1)
Medium Nessus Plugin ID 47108
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionAdrian Pastor and Tim Starling discovered that the CUPS web interface incorrectly protected against cross-site request forgery (CSRF) attacks. If an authenticated user were tricked into visiting a malicious website while logged into CUPS, a remote attacker could modify the CUPS configuration and possibly steal confidential data.
It was discovered that CUPS did not properly handle memory allocations in the texttops filter. If a user or automated system were tricked into printing a crafted text file, a remote attacker could cause a denial of service or possibly execute arbitrary code with privileges of the CUPS user (lp). (CVE-2010-0542)
Luca Carettoni discovered that the CUPS web interface incorrectly handled form variables. A remote attacker who had access to the CUPS web interface could use this flaw to read a limited amount of memory from the cupsd process and possibly obtain confidential data.
