Mandrake Linux Security Update Advisory
_______________________________________________________________________
Package name: rsync
Advisory ID: MDKSA-2003:111
Date: December 4th, 2003
Affected versions: 9.0, 9.1, 9.2, Corporate Server 2.1,
Multi Network Firewall 8.2
______________________________________________________________________
Problem Description:
A vulnerability was discovered in all versions of rsync prior to 2.5.7
that was recently used in conjunction with the Linux kernel do_brk()
vulnerability to compromise a public rsync server.
This heap overflow vulnerability, by itself, cannot yield root access,
however it does allow arbitrary code execution on the host running
rsync as a server. Also note that this only affects hosts running
rsync in server mode (listening on port 873, typically under xinetd).
