Debian Security Advisory
DSA-741-1 bzip2 -- infinite loop
- Date Reported:
- 07 Jul 2005
- Affected Packages:
- bzip2
- Vulnerable:
- Yes
- Security database references:
- In the Debian bugtracking system: Bug 310803.
In Mitre's CVE dictionary: CVE-2005-1260. - More information:
-
Chris Evans discovered that a specially crafted archive can trigger an infinite loop in bzip2, a high-quality block-sorting file compressor. During uncompression this results in an indefinitely growing output file which will finally fill up the disk. On systems that automatically decompress bzip2 archives this can cause a denial of service.
For the oldstable distribution (woody) this problem has been fixed in version 1.0.2-1.woody5.
For the stable distribution (sarge) this problem has been fixed in version 1.0.2-7.
For the unstable distribution (sid) this problem has been fixed in version 1.0.2-7.
We recommend that you upgrade your bzip2 package.
- Fixed in:
-
Debian GNU/Linux 3.0 (woody)
