Mandrake: Updated sharutils packages Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Mandrake Shaun Colley discovered a buffer overflow in shar that was triggered by output files (using -o) with names longer than 49 characters which could be exploited to run arbitrary attacker-specified code.

                 Mandrakelinux Security Update Advisory

 Package name:           sharutils
 Advisory ID:            MDKSA-2005:067
 Date:                   April 7th, 2005

 Affected versions:	 10.0, 10.1, Corporate 3.0,
			 Corporate Server 2.1

 Problem Description:

 Shaun Colley discovered a buffer overflow in shar that was triggered
 by output files (using -o) with names longer than 49 characters which
 could be exploited to run arbitrary attacker-specified code.
 Ulf Harnhammar discovered that shar does not check the data length
 returned by the wc command.
 Joey Hess discovered that unshar would create temporary files in an
 insecure manner which could allow a symbolic link attack to create or
 overwrite arbitrary files with the privileges of the user using unshar.
 The updated packages have been patched to correct these issues.
