Detail

Several vulnerabilities have been discovered in ekg, a console Gadu Gadu client, an instant messaging program. The Common Vulnerabilities and Exposures project identifies the following vulnerabilities:

CAN-2005-1850

Marcin Owsiany and Wojtek Kaniewski discovered insecure temporary file creation in contributed scripts.

CAN-2005-1851

Marcin Owsiany and Wojtek Kaniewski discovered potential shell command injection in a contributed script.

CAN-2005-1916

Eric Romang discovered insecure temporary file creation and arbitrary command execution in a contributed script that can be exploited by a local attacker.

The old stable distribution (woody) does not contain an ekg package.

For the stable distribution (sarge) these problems have been fixed in version 1.5+20050411-4.

For the unstable distribution (sid) these problems have been fixed in version 1.5+20050712+1.6rc2-1.

We recommend that you upgrade your ekg package.

Id Description
18072 ekg Unspecified Contributed Script Insecure Temporary File Creation
18071 ekg Unspecified Contributed Script Arbitrary Command Execution
17722 ekg linki.py Add-on Symlink Arbitrary File Manipulation

Eksperymentalny Klient Gadu-Gadu (EKG) contains a flaw that may allow a malicious local user to overwrite or create arbitrary files on the system. The issue is due to the czyjest and handle_keypress() functions in the contrib/scripts/linki.py script creating temporary files insecurely. It is possible for a user to use a symlink style attack from a critical EKG file to the /tmp/rmrmg_ekg_url file. When EKG is run, the temporary symlink file is activated with the privileges of the user running EKG, resulting in a loss of integrity.
