Description Matt Drew (RETIRED) gentoo-dev 2006-10-25 05:10:24 UTC
From secunia:

Description:
Some vulnerabilities have been reported in GNU Screen, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.

The vulnerabilities are caused due to errors within the handling of certain UTF-8 characters. This can be exploited to crash GNU Screen or potentially execute arbitrary code by printing a specially crafted string to the window.

The vulnerability is reported in versions prior to 4.0.3.

Solution:
Update to version 4.0.3.
Comment 1 Matt Drew (RETIRED) gentoo-dev 2006-10-25 05:14:28 UTC
Since the vulnerability is in UTF 8 character handling, a workaround might be to disable utf8 functionality.
Comment 2 Raphael Marichez (Falco) (RETIRED) gentoo-dev 2006-10-25 05:53:10 UTC
Hello !  mmm, err... let'me Cc the maintainer, otherwise we might wait a long time before someone bumps a new version :)

Comment 3 Sven Wegener gentoo-dev 2006-10-25 10:12:12 UTC
4.0.3 is in CVS
Comment 4 Matt Drew (RETIRED) gentoo-dev 2006-10-26 04:35:59 UTC
CC'ing arches for stabilization.
Comment 5 Christoph Mende (RETIRED) gentoo-dev 2006-10-26 05:01:29 UTC
- emerges fine on amd64
- passes collision-test
- passes multilib-strict
- works
