- Date Reported:
- 16 Jan 2002
- Affected Packages:
- at
- Vulnerable:
- Yes
- Security database references:
- In Mitre's CVE dictionary: CVE-2002-0004.
- More information:
-
zen-parse found a bug in the current implementation of at which leads into a heap corruption vulnerability which in turn could potentially lead into an exploit of the daemon user.
We recommend that you upgrade your at packages.
Unfortunately, the bugfix from DSA 102-1 wasn't propagated properly due to a packaging bug. While the file parsetime.y was fixed, and yy.tab.c should be generated from it, yy.tab.c from the original source was still used. This has been fixed in DSA-102-2.
- Fixed in:
-
Debian GNU/Linux 2.2 (potato)
