 Package name:           sysklogd
 Advisory ID:            MDKSA-2004:038
 Date:                   April 28th, 2004

 Affected versions:	 10.0, 9.1, 9.2, Corporate Server 2.1,
			 Multi Network Firewall 8.2
 ______________________________________________________________________

 Problem Description:

 Steve Grubb discovered a bug in sysklogd where it allocates an
 insufficient amount of memory which causes sysklogd to write to
 unallocated memory.  This could allow for a malicious user to crash
 sysklogd.
 
 The updated packages provide a patched sysklogd using patches from
 Openwall to correct the problem and also corrects the use of an
 unitialized variable (a previous use of "count").
