USN-1156-1: tgt vulnerabilities
21 June 2011
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04
- Ubuntu 10.10
An attacker could send crafted input to tgt and cause it to crash or run arbitrary programs.
- tgt - Linux SCSI target user-space tools
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)
The problem can be corrected by updating your system to the following package versions:
