CVE-2015-2327 Open this link in a new tabHow to fix?
Upgrade Debian:10 pcre3 to version 2:8.35-7.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pcre3 package and not the pcre3 package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
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.
