Mandrake Linux Security Update Advisory
______________________________________________________________________
Package name: libsafe
Advisory ID: MDKSA-2002:026
Date: April 11th, 2002
Affected versions: 7.1, 7.2, 8.0, 8.1, Corporate Server 1.0.1,
Single Network Firewall 7.2
______________________________________________________________________
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.
