Mandrake A memory starvation denial of service vulnerability in the ls program was discovered.

Hash: SHA1


                Mandrake Linux Security Update Advisory

 Package name:           fileutils/coreutils
 Advisory ID:            MDKSA-2003:106
 Date:                   November 12th, 2003

 Affected versions:	 9.0, 9.1, 9.2, Corporate Server 2.1,
			 Multi Network Firewall 8.2

 Problem Description:

 A memory starvation denial of service vulnerability in the ls program
 was discovered by Georgi Guninski.  It is possible to allocate a huge
 amount of memory by specifying certain command-line arguments.  It is
 also possible to exploit this remotely via programs that call ls such
 as wu-ftpd (although wu-ftpd is no longer shipped with Mandrake Linux).
 Likewise, a non-exploitable integer overflow problem was discovered in
 ls, which can be used to crash ls by specifying certain command-line
 arguments.  This can also be triggered via remotely accessible services
 such as wu-ftpd.
 The provided packages include a patched ls to fix these problems.
