Description

This security bulletin contains information about 1 vulnerability.


1) Use-after-free (CVE-ID: CVE-2026-33416)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to use-after-free in png_set_tRNS and png_set_PLTE when processing a crafted PNG file and subsequent decoding after png_free_data() or repeated setter calls. A remote attacker can supply a specially crafted PNG file to execute arbitrary code.

User interaction is required to open or process the crafted PNG file, and exploitation affects applications that free PNG data between png_read_info() and png_read_update_info().
