The remote host is missing an update to unzip announced via advisory DSA 903-1. Imran Ghory discovered a race condition in the permissions setting code in unzip. When decompressing a file in a directory an attacker has access to, unzip could be tricked to set the file permissions to a different file the user has permissions to. For the old stable distribution (woody) this problem has been fixed in version 5.50-1woody4.

For the stable distribution (sarge) this problem has been fixed in version 5.52-1sarge2. For the unstable distribution (sid) this problem has been fixed in version 5.52-4. We recommend that you upgrade your unzip package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20903-1
