Debian Linux Security Advisory 3031-1 - The Google Security Team discovered a buffer overflow vulnerability in the HTTP transport code in apt-get. An attacker able to man-in-the-middle a HTTP request to an apt repository can trigger the buffer overflow, leading to a crash of the 'http' apt method binary, or potentially to arbitrary code execution.

Ubuntu Security Notice 2353-1 - It was discovered that APT incorrectly handled certain http URLs. If a remote attacker were able to perform a man-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. 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. Various other issues were also addressed.
