Centericq: Remote buffer overflow in LiveJournal handling


1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 200701-20 / centericq
Release Date January 24, 2007
Latest Revision January 24, 2007: 01
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
net-im/centericq <= 4.21.0-r2 All supported architectures

Related bugreports: #160793


Centericq does not properly handle communications with the LiveJournal service, allowing for the remote execution of arbitrary code.

2.  Impact Information


Centericq is a text mode menu-driven and window-driven instant messaging interface.


When interfacing with the LiveJournal service, Centericq does not appropriately allocate memory for incoming data, in some cases creating a buffer overflow.


An attacker could entice a user to connect to an unofficial LiveJournal server causing Centericq to read specially crafted data from the server, which could lead to the execution of arbitrary code with the rights of the user running Centericq.

3.  Resolution Information


There is no known workaround at this time.


Currently, Centericq is unmaintained. As such, Centericq has been masked in Portage until it is again maintained.

Code Listing 3.1: Resolution

# emerge --ask --verbose --unmerge "net-im/centericq"
