CVE-2005-0199: Barton Ngircd

Critical severity, CVSS 9.8. EPSS: 18.8% chance of exploitation in the next 30 days.

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.

Affected products

• Barton Ngircd: before 0.8.2 (fixed in 0.8.2)
