Severity: normal
Exploitable: remote
Date: August 05, 2004
Bug(s): #59424
ID: 200408-03
Synopsis
libpng contains numerous vulnerabilities potentially allowing an attacker to perform a Denial of Service attack or even execute arbitrary code.
Background
libpng is a standard library used to process PNG (Portable Network Graphics) images. It is used by several other programs, including web browsers and potentially server processes.
Affected Packages
Package: media-libs/libpng
Vulnerable: <= 1.2.5-r7
Unaffected: >= 1.2.5-r8
Architectures: All supported architectures
Description
libpng contains numerous vulnerabilities including null pointer dereference errors and boundary errors in various functions.
Impact
An attacker could exploit these vulnerabilities to cause programs linked against the library to crash or execute arbitrary code with the permissions of the user running the vulnerable program, which could be the root user.
Workaround
There is no known workaround at this time. All users are encouraged to upgrade to the latest available version.
Resolution
All libpng users should upgrade to the latest stable version: Code: | # emerge sync
# emerge -pv ">=media-libs/libpng-1.2.5-r8"
# emerge ">=media-libs/libpng-1.2.5-r8" | You should also run revdep-rebuild to rebuild any packages that depend on older versions of libpng :
