CVE-2015-2327 low priority: Debian including 1 source packages (pcre3), 2 status rows across 2 suites (bookworm, bullseye): resolved 2.
PCRE before 8.36 mishandles the /(((a\2)|(a*)\g<-1>))*/ pattern and related patterns with certain internal recursive back references, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
