Title: MPFR: User-assisted execution of arbitrary code (GLSA 201512-06)
Severity: normal
Exploitable: remote
Date: December 30, 2015
Bug(s): #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: dev-libs/mpfr
Vulnerable: < 3.1.3_p4
Unaffected: >= 3.1.3_p4
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/mpfr-3.1.3_p4"
