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

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Adrian 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.
(CVE-2010-0540)

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.
(CVE-2010-1748).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
