CVE-2017-9224

Published: 24 May 2017

An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds read occurs in match_at() during regular expression searching. A logical error involving order of validation and access in match_at() could result in an out-of-bounds read from a stack buffer.

From the Ubuntu Security Team

It was discovered that Oniguruma incorrectly handled certain regular expressions. An attacker could possibly use this issue to obtain sensitive information, cause a denial of service or execute arbitrary code.
