Package : lintian
Vulnerability : insecure temporary directory
Problem-Type : local
Debian-specific: yes
CVE ID : CAN-2004-1000
Debian Bug : 286681
Jeroen van Wolffelaar discovered a problem in lintian, the Debian
package checker. The program removes the working directory even if it
wasn't created at program start, removing an unrelated file or
directory a malicious user inserted via a symlink attack.
For the stable distribution (woody) this problem has been fixed in
version 1.20.17.1.
For the unstable distribution (sid) this problem has been fixed in
version 1.23.6.
We recommend that you upgrade your lintian package.
