"Marek Kroemeke discovered that the mod_proxy module incorrectly
handled certain requests. A remote attacker could use this issue to
cause the server to stop responding, leading to a denial of service.
This issue only affected Ubuntu 14.04 LTS. (CVE-2014-0117)

Giancarlo Pellegrino and Davide Balzarotti discovered that the
mod_deflate module incorrectly handled body decompression. A remote
attacker could use this issue to cause resource consumption, leading
to a denial of service. (CVE-2014-0118)

Marek Kroemeke and others discovered that the mod_status module
incorrectly handled certain requests. A remote attacker could use this
issue to cause the server to stop responding, leading to a denial of
service, or possibly execute arbitrary code. (CVE-2014-0226)

Rainer Jung discovered that the mod_cgid module incorrectly handled
certain scripts. A remote attacker could use this issue to cause the
server to stop responding, leading to a denial of service.
(CVE-2014-0231).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
