CVE-2023-2731 (GCVE-0-2023-2731)

Vulnerability from cvelistv5 – Published: 2023-05-17 00:00 – Updated: 2025-01-22 18:22

Summary

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)
