CVE-2005-0199

CWE-191Published: May 2, 2005· Updated: Jun 16, 2026

9.8

CVSS v3.1

Official Description

Integer underflow in the Lists_MakeMask() function in lists.c in ngIRCd before 0.8.2 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a long MODE line that causes an incorrect length calculation, which leads to a buffer overflow.

Technical Analysis

CVE-2005-0199 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

A proof-of-concept (PoC) exploit exists for CVE-2005-0199. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
