NVD Description

Note: Versions mentioned in the description apply to the upstream pcre3 package. See Remediation section below for Debian:9 relevant versions.

The match function in pcre_exec.c in PCRE before 8.37 mishandles the /(?:((abcd))|(((?:(?:(?:(?:abc|(?:abcdef))))b)abcdefghi)abc)|((*ACCEPT)))/ pattern and related patterns involving (*ACCEPT), which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (partially initialized memory and application crash) via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror, aka ZDI-CAN-2547.

Remediation

Upgrade Debian:9 pcre3 to version 2:8.35-7.2 or higher.
