NVD Description

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

pcre_jit_compile.c in PCRE 8.35 does not properly use table jumps to optimize nested alternatives, which allows remote attackers to cause a denial of service (stack memory corruption) or possibly have unspecified other impact via a crafted string, as demonstrated by packets encountered by Suricata during use of a regular expression in an Emerging Threats Open ruleset.

Remediation

Upgrade Debian:9 pcre3 to version 2:8.38-1 or higher.
