Description:
Multiple vulnerabilities have been identified in mod_gzip possibly allowing malicious people to gain system access.
The problems only occur when mod_gzip is configured to run in debug mode.
It is possible to cause a buffer overflow by requesting a filename longer than 2048 characters.
A format string vulnerability exist in the handling of log entries. This is exploitable if Apache log is enabled.
When Apache log isn't used, mod_gzip logs to "/tmp" in an insecure way allowing a race condition.
Solution:
Do not use mod_gzip in debug mode on production sites.
