Package : unarj
Vulnerability : several
Problem-Type : local (remote)
Debian-specific: no
CVE ID : CAN-2004-0947 CAN-2004-1027
Debian Bug : 281922
Several vulnerabilities have been discovered in unarj, a non-free ARJ
unarchive utility. The Common Vulnerabilities and Exposures Project
identifies the following vulnerabilities:
CAN-2004-0947
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.
CAN-2004-1027
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.
