1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
dev-libs/mpfr	< 2.4.1	>= 2.4.1	All supported architectures

Related bugreports: #260968

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

2. Impact Information

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

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

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

3. Resolution Information

There is no known workaround at this time.

All MPRF users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
