EPSS: 1.5% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2017-03-18 · updated 2026-06-17
Weakness: CWE-119

Description

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.

Affected products

Erlang OTP: 18.0, 18.0-rc1, 18.0-rc2, 18.0.1, 18.0.2, 18.0.3 (+61)
