Debian Linux project released today bug fixes for lighttpd and gaim package.
Gaim packages fix execution of arbitrary code
It was discovered that gaim, an multi-protocol instant messaging client, was vulnerable to several integer overflows in its MSN protocol handlers. These could allow a remote attacker to execute arbitrary code.
lighttpd packages fix multiple DOS issues
Several local/remote vulnerabilities have been discovered in lighttpd, a fast webserver with minimal memory footprint.
a) lighttpd 1.4.18, and possibly other versions before 1.5.0, does not properly calculate the size of a file descriptor array, which allows remote attackers to cause a denial of service (crash) via a large number of connections, which triggers an out-of-bounds access.
b) connections.c in lighttpd before 1.4.16 might accept more connections than the configured maximum, which allows remote attackers to cause a denial of service (failed assertion) via a large number of connection attempts.
How do I fix lighttpd and gaim security issues?
First, update the internal database, enter:
# apt-get update
Install corrected packages, enter:
# apt-get upgrade
