Description

From Red Hat Security Advisory 2018:2737 :

An update for mod_perl is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Mod_perl incorporates a Perl interpreter into the Apache web server, such that the Apache HTTP server can directly execute Perl code.

Security Fix(es) :

  • mod_perl: arbitrary Perl code execution in the context of the user account via a user-owned .htaccess (CVE-2011-2767)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
