 Package : pxelinux
 Date    : November 16, 2006
 Affected: 2006.0, Corporate 4.0
 _______________________________________________________________________
 
 Problem Description:
 
 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 allows 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.
