The upstream developers discovered a problem in cabextract, a tool to extract cabinet files. The program was able to overwrite files in upper directories. This could lead an attacker to overwrite arbitrary files. For the stable distribution (woody) this problem has been fixed in version 0.2-2b. For the unstable distribution (sid) this problem has been fixed in version 1.1-1. We recommend that you upgrade your cabextract package.
