Synopsis

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

2. Impact Information

Background

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

Description

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

Impact

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

Workaround

There is no known workaround at this time.

Resolution

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"
