PatchTheCVECVE-2006-2656: Stack-based buffer overflow in the tiffsplit command in libtiff 3.8.2 and earlier might might allow attackers
CVE-2006-2656 is a high-severity flaw (CVSS 7.5) affecting libtiff. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Stack-based buffer overflow in the tiffsplit command in libtiff 3.8.2 and earlier might might allow attackers to execute arbitrary code via a long filename. NOTE: tiffsplit is not setuid. If there is not a common scenario under which tiffsplit is called with attacker-controlled command line arguments, then perhaps this issue should not be included in CVE.
