Detailsinfo

A vulnerability was found in hanterm-xf 2.0. It has been rated as problematic. Affected by this issue is an unknown functionality of the component DEC UDK Processor. The manipulation with an unknown input leads to a infinite loop vulnerability. Using CWE to declare the problem leads to CWE-835. The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. Impacted is availability. CVE summarizes:

The DEC UDK processing feature in the hanterm (hanterm-xf) terminal emulator before 2.0.5 allows attackers to cause a denial of service via a certain character escape sequence that causes the terminal to enter a tight loop.

The bug was discovered 02/24/2003. The weakness was presented 06/06/2003 by H D Moore (DiGiT) with Digital Defense (Website). The advisory is shared for download at cve.mitre.org. This vulnerability is handled as CVE-2003-0079. The exploitation is known to be easy. The attack needs to be approached locally. No form of authentication is required for exploitation. Technical details are unknown but an exploit is available.

After even before and not, there has been an exploit disclosed. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 7 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 15217 (Debian DSA-380-1 : xfree86 - buffer overflows, denial of service), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115023 (Red Hat Hangul Terminal Package Multiple Vulnerabilities).
