Ubuntu Security Notice USN-1156-1
June 21, 2011
tgt vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04
- Ubuntu 10.10
Summary:
An attacker could send crafted input to tgt and cause it to crash or run
arbitrary programs.
Software Description:
- tgt: Linux SCSI target user-space tools
Details:
It was discovered that tgt incorrectly handled long iSCSI name strings, and
invalid PDUs. A remote attacker could exploit this to cause tgt to crash,
resulting in a denial of service, or possibly execute arbitrary code. This
issue only affected Ubuntu 10.10. (CVE-2010-2221)
Emmanuel Bouillon discovered that tgt incorrectly handled certain iSCSI
logins. A remote attacker could exploit this to cause tgt to crash,
resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2011-0001)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.04:
tgt 1:1.0.13-0ubuntu2.1
Ubuntu 10.10:
tgt 1:1.0.4-1ubuntu4.1
In general, a standard system update will make all the necessary changes.
