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
-------------------------------------------------------------------
1 dev-libs/mpfr < 3.1.3_p4 >= 3.1.3_p4

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"
