CVE-2015-5073: IBM Powerkvm

Critical severity, CVSS 9.1. EPSS: 7.7% chance of exploitation in the next 30 days.

Heap-based buffer overflow in the find_fixedlength function in pcre_compile.c in PCRE before 8.38 allows remote attackers to cause a denial of service (crash) or obtain sensitive information from heap memory and possibly bypass the ASLR protection mechanism via a crafted regular expression with an excess closing parenthesis.

Affected products

• IBM Powerkvm: version 2.1 only; version 3.1 only
• Pcre Pcre: up to and including 8.37
