FreeBSD : apache22 -- several vulnerabilities (f927e06c-1109-11e4-b090-20cf30e32f6d)

Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Apache HTTP SERVER PROJECT reports :

mod_deflate: The DEFLATE input filter (inflates request bodies) now
limits the length and compression ratio of inflated request bodies to
avoid denial of service via highly compressed bodies. See directives
DeflateInflateLimitRequestBody, DeflateInflateRatioLimit, and
DeflateInflateRatioBurst.

mod_cgid: Fix a denial of service against CGI scripts that do not
consume stdin that could lead to lingering HTTPD child processes
filling up the scoreboard and eventually hanging the server. By
default, the client I/O timeout (Timeout directive) now applies to
communication with scripts. The CGIDScriptTimeout directive can be
used to set a different timeout for communication with scripts.

Fix a race condition in scoreboard handling, which could lead to a
heap buffer overflow.

core: HTTP trailers could be used to replace HTTP headers late during
request processing, potentially undoing or otherwise confusing modules
that examined or modified request headers earlier. Adds
'MergeTrailers' directive to restore legacy behavior.
