Gentoo: GLSA-201207-09: mod_fcgid: Multiple vulnerabilities
Summary
Multiple vulnerabilities have been found in mod_fcgid:
* An error in the "fcgid_header_bucket_read()" function in
fcgid_bucket.c could cause a stack-based buffer overflow
(CVE-2010-3872).
* An error in the "is_spawn_allowed() function in fcgid_spawn_ctl.c
prevents Apache from recognizing the FcgidMaxProcessesPerClass
directive for a virtual host (CVE-2012-1181).
Resolution
All mod_fcgid users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_fcgid-2.3.7"
