Debian Security Advisory DSA-2023-1 security@debian.org
http://www.debian.org/security/ Steffen Joeris
March 28, 2010 http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package : curl
Vulnerability : buffer overflow
Problem type : local (remote)
Debian-specific: no
CVE Id : CVE-2010-0734

Wesley Miaw discovered that libcurl, a multi-protocol file transfer
library, is prone to a buffer overflow via the callback function when
an application relies on libcurl to automatically uncompress data. Note
that this only affects applications that trust libcurl's maximum limit
for a fixed buffer size and do not perform any sanity checks themselves.


For the stable distribution (lenny), this problem has been fixed in
version 7.18.2-8lenny4.

Due to a problem with the archive software, we are unable to release all
architectures simultaneously. Binaries for the hppa, ia64, mips, mipsel
and s390 architectures will be provided once they are available.

For the testing distribution (squeeze) and the unstable distribution
(sid), this problem has been fixed in version 7.20.0-1.


We recommend that you upgrade your curl packages.


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.
