Detail

Synopsis

A buffer overflow in Apache mod_fcgid might allow remote attackers to execute arbitrary code or cause a Denial of Service condition.

Background

Apache mod_fcgid is a binary-compatible alternative to mod_fastcgi with better process management.

Description

Apache mod_fcgid fails to perform a boundary check on user-supplied input, potentially resulting in a heap-based buffer overflow.

Impact

A remote attacker can supply a crafted input, possibly resulting in execution of arbitrary code or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Apache mod_fcgid users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_fcgid-2.3.9"
