Title:	MPFR: User-assisted execution of arbitrary code
Date:	12/30/2015
Bugs:	#532028
ID:	201512-06

Synopsis

A buffer overflow vulnerability in MPFR could allow remote attackers to execute arbitrary code or cause Denial of Service.

Background

MPFR is a library for multiple-precision floating-point computations with exact rounding.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-libs/mpfr	< 3.1.3_p4	>= 3.1.3_p4	All supported architectures

Description

MPFR fails to adequately check user-supplied input, which could lead to a buffer overflow.

Impact

A remote attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All MPFR users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/mpfr-3.1.3_p4"
