Detail

Synopsis

Multiple buffer overflows in MPFR might lead to a Denial of Service.

Background

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

Description

Multiple buffer overflows have been reported in the mpfr_snprintf() and mpfr_vsnprintf() functions.

Impact

A remote user could exploit the vulnerability to cause a Denial of Service in an application using MPFR via unknown vectors.

Workaround

There is no known workaround at this time.

Resolution

All MPRF users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/mpfr-2.4.1"
