USN-46-1: TIFF library vulnerability
22 December 2004
TIFF library vulnerability
Releases
Details
A 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.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 4.10
-
libtiff4
-
In general, a standard system update will make all the necessary changes.
