Debian Security Advisory DSA 996-1 [email protected]
http://www.debian.org/security/ Martin Schulze

- --------------------------------------------------------------------------
Package : libcrypt-cbc-perl
Vulnerability : programming error
Problem type : remote
Debian-specific: no
CVE ID : CVE-2006-0898
Lincoln Stein discovered that the Perl Crypt::CBC module produces weak
ciphertext when used with block encryption algorithms with blocksize >
8 bytes.
The old stable distribution (woody) does not contain a Crypt::CBC module.
For the stable distribution (sarge) this problem has been fixed in
version 2.12-1sarge1.
For the unstable distribution (sid) this problem has been fixed in
version 2.17-1.
We recommend that you upgrade your libcrypt-cbc-perl 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
