Apache Software Foundation mod_fcgid

A security Bypass vulnerability exists in the FcgidPassHeader Proxy in mod_fcgid through 2016-07-07.

Heap-based buffer overflow in the fcgid_header_bucket_read function in fcgid_bucket.c in the mod_fcgid module before 2.3.9 for the Apache HTTP Server allows remote attackers to have an unspecified impact via unknown vectors.

Httpd: mod_fcgid: stack-based buffer overflow in fcgid_header_bucket_read() in modules/fcgid/fcgid_bucket.c

fcgid_spawn_ctl.c in the mod_fcgid module 2.3.6 for the Apache HTTP Server does not recognize the FcgidMaxProcessesPerClass directive for a virtual host, which makes it easier for remote attackers to cause a denial of service (memory consumption) via a series of HTTP requests that triggers a process count higher than the intended limit.
