CVE-2016-10253

9.8 criticalEPSS 1.5%

Critical (9.8) in erlang erlang\/otp. EPSS 1.5% chance of exploitation in the next 30 days.

An issue was discovered in Erlang/OTP 18.x. Erlang's generation of compiled regular expressions is vulnerable to a heap overflow. Regular expressions using a malformed extpattern can indirectly specify an offset that is used as an array index. This ordinal permits arbitrary regions within the erts_alloc arena to be both read and written to.
