CVE-2005-0199 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 18.77% chance of exploitation in the next 30 days.
