CVE-2015-2305 is a vulnerability of currently unknown severity. Integer overflow in the regcomp implementation in the Henry Spencer BSD regex library (aka rxspencer) alpha3.8.g5 on 32-bit platforms, as used in NetBSD through 6.1.5 and other products, might allow context-dependent attackers to execute arbitrary code via a large regular expression that leads to a heap-based buffer overflow.. EPSS estimates a 8.37% chance of exploitation in the next 30 days.
