Debian Security Advisory DSA 903-1 [email protected]

Package : unzip
Vulnerability : race condition
Problem type : local
Debian-specific: no
CVE ID : CAN-2005-2475
BugTraq ID : 14450
Debian Bug : 321927
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.
Upgrade Instructions
- --------------------
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
