- Date Reported:
- 13 Dec 2016
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2016-1252.
- More information:
Jann Horn of Google Project Zero discovered that APT, the high level package manager, does not properly handle errors when validating signatures on InRelease files. An attacker able to man-in-the-middle HTTP requests to an apt repository that uses InRelease files (clearsigned Release files), can take advantage of this flaw to circumvent the signature of the InRelease file, leading to arbitrary code execution.
For the stable distribution (jessie), this problem has been fixed in version 126.96.36.199.4.
For the unstable distribution (sid), this problem has been fixed in version 1.4~beta2.
We recommend that you upgrade your apt packages.
