CVE-2017-9228
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 heap out-of-bounds write occurs in bitset_set_range() during regular expression compilation due to an uninitialized variable from an incorrect state transition. An incorrect state transition in parse_char_class() could create an execution path that leaves a critical local variable uninitialized until it's used as an index, resulting in an out-of-bounds write memory corruption.
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.
