Mandriva Advisories

Package name libsafe
Date April 11th, 2002
Advisory ID MDKSA-2002:026
Affected versions 7.1, 7.2, 8.0, 8.1, 8.2, CS1.0
Synopsis Updated libsafe packages fix inadequate format string protection

Problem Description

Wojciech Purczynski discovered that format string protection in libsafe
can be easily bypassed by using flag characters that are implemented in
glibc but are not implemented in libsafe. It was also discovered that
*printf function wrappers incorrectly parse argument indexing in format
strings, making some incorrect assumptions on the number of arguments
and conversion specifications.

These problems were fixed by the libsafe authors in 2.0-12.
