CVE-2010-2221: Buffer Overflow

First published: Wed May 19 2010(Updated: )

It was reported that a stack buffer overflow vulnerability exists in multiple implementations of iSCSI target, including scsi-target-utils. A missing bounds check when handling SCN messages could result in a buffer overflow when the iSCSI Name string is longer than 1008 bytes, which could lead to corruption of sensitive stack data. During investigation, more buffer overflow vulnerabilities were discovered as well. Acknowledgements: Red Hat would like to thank the Vulnerability Research Team at TELUS Security Labs and Fujita Tomonori for responsibly reporting these flaws.
