MDKSA-2006:211: pxelinux

Vulnerability Assessment Summary
Check for the version of the pxelinux package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory MDKSA-2006:211 (pxelinux).

PXELINUX is a PXE bootloader. It is built with a private copy of
libpng, and as such could be susceptible to some of the same
vulnerabilities:
Buffer overflow in the png_decompress_chunk function in pngrutil.c in
libpng before 1.2.12 permits context-dependent attackers to cause a
denial of service and possibly execute arbitrary code via unspecified
vectors related to 'chunk error processing,' possibly involving the
'chunk_name'. (CVE-2006-3334)
It is questionable whether this issue is actually exploitable, but the
patch to correct the issue has been included in versions < 1.2.12.
Tavis Ormandy, of the Gentoo Linux Security Auditing Team, discovered a
typo in png_set_sPLT() that may cause an application using libpng to
read out of bounds, resulting in a crash. (CVE-2006-5793)
Packages have been patched to correct these issues.
