Buffer overflow in the HTTP transport code in apt-get in APT 1.0.1 and earlier allows man-in-the-middle attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted URL.

Affected: Ubuntu:14.04:LTS: apt

It was discovered that APT incorrectly handled certain http URLs. If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be exploited to cause APT to crash, resulting in a denial of service, or possibly execute arbitrary code. The default compiler options for affected releases should reduce the vulnerability to a denial of service. (CVE-2014-6273)

In addition, this update fixes regressions introduced by the USN-2348-1 security update: APT incorrectly handled file:/// sources on a different partition, incorrectly handled Dir::state::lists set to a relative path, and incorrectly handled cdrom: sources.
