Libtiff · Libtiff · CVE-2022-34266
**Name of the Vulnerable Software and Affected Versions**
LibTIFF version 4.0.3-35.amzn2.0.1
**Description**
The issue is related to the processing of malicious TIFF files, which can cause a denial of service (application crash). Specifically, an invalid range may be passed as an argument to the `memset()` function within the `TIFFFetchStripThing()` function in `tif dirread.c`, leading to a segfault after the use of an uninitialized resource. This occurs when the `TIFFFetchStripThing()` function is used to handle TIFF files, potentially allowing an attacker to exploit the vulnerability and cause a service disruption.
**Recommendations**
For LibTIFF version 4.0.3-35.amzn2.0.1, consider avoiding the use of the `TIFFFetchStripThing()` function until a patch is available, or restrict access to the `tif dirread.c` module to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
