- Several vulnerabilities have been discovered in unarj, a non-free ARJ
- unarchive utility. The Common Vulnerabilities and Exposures Project
- identifies the following vulnerabilities:
- A buffer overflow has been discovered when handling long file
- names contained in an archive. An attacker could create a
- specially crafted archive which could cause unarj to crash or
- possibly execute arbitrary code when being extracted by a victim.
- A directory traversal vulnerability has been found so that an
- attacker could create a specially crafted archive which would
- create files in the parent directory when being extracted by a
- victim. When used recursively, this vulnerability could be used
- to overwrite critical system files and programs.
- For the stable distribution (woody) these problems have been fixed in
- version 2.43-3woody1.
- For the unstable distribution (sid) these problems don\'t apply since
- unstable/non-free does not contain the unarj package.
- We recommend that you upgrade your unarj package.
