mount
SuSE Security Announcement
Package: util < 2.10f
Date: Thu Feb 10 20:03:43 CET 2000
Affected SuSE versions: all
Vulnerability Type: (unlikely) local root compromise
SuSE default package: yes
Other affected systems: all linux systems using util < 2.10f
A security hole was discovered in the package mentioned above.
Please update it as soon as possible or disable the service if you
are using this software on your SuSE Linux installation(s).
Other Linux distributions or operating systems might be affected
as well, please contact your vendor for information about this
issue.
Please note that we provide this information on an “as-is” basis
only. There is no warranty whatsoever and no liability for any
direct, indirect or incidental damage arising from this information
or the installation of the update package.
1. Problem Description
The mount/umount command doesn’t do proper bounds checking on
user input.
2. Impact
If an attacker executes mount/umount with a long relative
pathname, it will overwrite dynamic allocated memory of the
realpath function. It is possible that an attacker could gain root
privileges by modifying the heap data, however we were not able to
exploit it.
3. Solution
Update the package from our FTP server or remove the suid
bits.
Please verify these md5 checksums of the updates before
installing: (For SuSE 6.0, please use the 6.1 updates)
