[Pkg-cups-devel] Bug#457453: cupsys: CVE-2007-5849 stack-based buffer overflow leading to code execution in SNMP back-end

[Nico Golde]

Package: cupsys
Version: 1.2.7-4etch1
Severity: grave
Tags: security patch

Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for cupsys.

CVE-2007-5849[0]:
| Integer underflow in the asn1_get_string function in the SNMP back end
| for CUPS allows remote attackers to execute arbitrary code via a
| crafted SNMP response that triggers a stack-based buffer overflow.

I attached a patch which fixes this problem.
Sarge is not affected by this as the SNMP backend was 
introduced later.

If you fix this vulnerability please also include the CVE id
in your changelog entry.

For further information:

Kind regards
Nico
