-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3213-1 security@xxxxxxxxxx http://www.debian.org/security/ Salvatore Bonaccorso April 06, 2015 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : arj CVE ID : CVE-2015-0556 CVE-2015-0557 CVE-2015-2782 Debian Bug : 774015 774434 774435 Multiple vulnerabilities have been discovered in arj, an open source version of the arj archiver. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2015-0556 Jakub Wilk discovered that arj follows symlinks created during unpacking of an arj archive. A remote attacker could use this flaw to perform a directory traversal attack if a user or automated system were tricked into processing a specially crafted arj archive. CVE-2015-0557 Jakub Wilk discovered that arj does not sufficiently protect from directory traversal while unpacking an arj archive containing file paths with multiple leading slashes. A remote attacker could use this flaw to write to arbitrary files if a user or automated system were tricked into processing a specially crafted arj archive. CVE-2015-2782 Jakub Wilk and Guillem Jover discovered a buffer overflow vulnerability in arj. A remote attacker could use this flaw to cause an application crash or, possibly, execute arbitrary code with the privileges of the user running arj. For the stable distribution (wheezy), these problems have been fixed in version 3.10.22-10+deb7u1. For the upcoming stable distribution (jessie), these problems have been fixed in version 3.10.22-13. For the unstable distribution (sid), these problems have been fixed in version 3.10.22-13. We recommend that you upgrade your arj packages.
