Slackware Security Advisory: 2004-222-01 Moderate libpng Overflow Issue

slackware
Calendar Grey August 10, 2004
Dist Slackware Esm H88
Fresh libpng updates are now available for Slackware users. These improvements address vulnerabilities that could lead to application failures and unauthorized code execution.
New libpng packages are available for Slackware 8.1, 9.0, 9.1, 10.0, and -current to fix security issues

Summary

Here are the details from the Slackware 10.0 ChangeLog: Sat Aug 7 17:17:20 PDT 2004 patches/packages/libpng-1.2.5-i486-3.tgz: Patched possible security issues including buffer and integer overflows and null pointer references. These issues could cause program crashes, or possibly allow arbitrary code embedded in a malicious PNG image to execute. The PNG library is widely used within the system, so all sites should upgrade to the new libpng package.
