Package	Vulnerable versions	Unaffected versions	Architecture(s)

Synopsis

CenterICQ is vulnerable to a Denial of Service issue, and also potentially to the execution of arbitrary code through an included vulnerable ktools library.

2. Impact Information

Background

CenterICQ is a text-based instant messaging interface that supports multiple protocols. It includes the ktools library, which provides text-mode user interface controls.

Description

Gentoo developer Wernfried Haas discovered that when the "Enable peer-to-peer communications" option is enabled, CenterICQ opens a port that insufficiently validates whatever is sent to it. Furthermore, Zone-H Research reported a buffer overflow in the ktools library.

Impact

A remote attacker could cause a crash of CenterICQ by sending packets to the peer-to-peer communications port, and potentially cause the execution of arbitrary code by enticing a CenterICQ user to edit overly long contact details.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All CenterICQ users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-im/centericq-4.21.0-r2"
