Ubuntu 4.10 : tiff vulnerability (USN-46-1)
Critical Nessus Plugin ID 20663
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionA buffer overflow was discovered in the TIFF library. A TIFF file includes a value indicating the number of 'directory entry' header fields contained in the file. If this value is -1, an invalid memory allocation was performed. A malicious image could be constructed which, when decoded, would have resulted in execution of arbitrary code with the privileges of the process using the library.
Since this library is used in many applications like 'ghostscript' and the 'CUPS' printing system, this vulnerability may lead to remotely induced privilege escalation.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected libtiff-tools, libtiff4 and / or libtiff4-dev packages.
