CVE-2017-9229
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 SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg->dmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition.
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.
