Synopsis
The remote Gentoo host is missing one or more security-related patches.
Description
The remote host is affected by the vulnerability described in GLSA-200804-01 (CUPS: Multiple vulnerabilities)
Multiple vulnerabilities have been reported in CUPS:
regenrecht (VeriSign iDefense) discovered that the cgiCompileSearch() function used in several CGI scripts in CUPS' administration interface does not correctly calculate boundaries when processing a user-provided regular expression, leading to a heap-based buffer overflow (CVE-2008-0047).
Helge Blischke reported a double free() vulnerability in the process_browse_data() function when adding or removing remote shared printers (CVE-2008-0882).
Tomas Hoger (Red Hat) reported that the gif_read_lzw() function uses the code_size value from GIF images without properly checking it, leading to a buffer overflow (CVE-2008-1373).
An unspecified input validation error was discovered in the HP-GL/2 filter (CVE-2008-0053).
Impact :
A local attacker could send specially crafted network packets or print jobs and possibly execute arbitrary code with the privileges of the user running CUPS (usually lp), or cause a Denial of Service. The vulnerabilities are exploitable via the network when CUPS is sharing printers remotely.
Workaround :
There is no known workaround at this time.
Solution
All CUPS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-print/cups-1.2.12-r7'
