Synopsis
========

An integer overflow in musl might allow an attacker to execute
arbitrary code.

Background
==========

musl is a “libc”, an implementation of the standard library
functionality described in the ISO C and POSIX standards, plus common
extensions, intended for use on Linux-based systems.

Affected packages
=================

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 sys-libs/musl < 1.1.15-r2 >= 1.1.15-r2

Description
===========

A vulnerability was discovered in musl’s tre_tnfa_run_parallel function
buffer overflow logic, due to the incorrect use of integer types and
missing overflow checks.

Impact
======

An attacker, who controls the regular expression and/or string being
searched, could execute arbitrary code with the privileges of the
process.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All musl users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=sys-libs/musl-1.1.15-r2”

References
