CVE-2015-8389
pcre: infinite recursion in JIT compiler when processing certain patterns (8.38/21)
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon NVD. Plus basse selon Red Hat (moyenne), Ubuntu (faible).
Description
PCRE before 8.38 mishandles the /(?:|a|){100}x/ pattern and related patterns, which allows remote attackers to cause a denial of service (infinite recursion) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
