HIGHCVSS 2.0
EPSS 4.44%
Description
The pcre_exec function in pcre_exec.c in PCRE before 8.38 mishandles a // pattern with a \01 string, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
