Package : gzip
Vulnerability : Potential buffer overflow
Problem-Type : local
Debian-specific: no
GOBBLES found a buffer overflow in gzip that occurs when compressing
files with really long filenames. Even though GOBBLES claims to have
developed an exploit to take advantage of this bug, it has been said
by others that this problem is not likely to be exploitable as other
security incidents.
Additionally, the Debian version of gzip from the stable release does
not segfault, and hence does not directly inherit this problem.
However, better be safe than sorry, so we have prepared an update for
you.
Please make sure you are running an up-to-date version from
stable/unstable/testing with at least version 1.2.4-33.
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.
