GHSA-G995-H8WX-7QW6

Vulnerability from github – Published: 2023-05-18 00:30 – Updated: 2024-04-04 04:14

Details

A NULL pointer dereference flaw was found in Libtiff's LZWDecode() function in the libtiff/tif_lzw.c file. This flaw allows a local attacker to craft specific input data that can cause the program to dereference a NULL pointer when decompressing a TIFF format file, resulting in a program crash or denial of service.

Severity ?

5.5 (Medium)
