RedHat: Moderate: mod_perl security update
Summary
Summary
Mod_perl incorporates a Perl interpreter into the Apache web server, so that the Apache HTTP server can directly execute Perl code. The Apache::PerlRun module was found to not properly escape PATH_INFO before being used in a regular expression. If a server is configured to use Apache::PerlRun, an attacker could request a carefully crafted URI causing resource consumption, which could lead to a denial of service (CVE-2007-1349). Users of mod_perl should update to these erratum packages which contain a backported fix to correct this issue.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
