Summary
The remote host is missing an update to tiff announced via advisory DSA 1137-1. Tavis Ormandy of the Google Security Team discovered several problems in the TIFF library. The Common Vulnerabilities and Exposures project identifies the following issues: CVE-2006-3459 Several stack-buffer overflows have been discovered. CVE-2006-3460 A heap overflow vulnerability in the JPEG decoder may overrun a buffer with more data than expected. CVE-2006-3461 A heap overflow vulnerability in the PixarLog decoder may allow an attacker to execute arbitrary code. CVE-2006-3462 A heap overflow vulnerability has been discovered in the NeXT RLE decoder. CVE-2006-3463 An loop was discovered where a 16bit unsigned short was used to iterate over a 32bit unsigned value so that the loop would never terminate and continue forever. CVE-2006-3464 Multiple unchecked arithmetic operations were uncovered, including a number of the range checking operations designed to ensure the offsets specified in TIFF directories are legitimate. CVE-2006-3465 A flaw was also uncovered in libtiffs custom tag support which may result in abnormal behaviour, crashes, or potentially arbitrary code execution.
