Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2026-20884)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the deflate_dng_load_raw functionality. A remote attacker can pass specially crafted file, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Heap-based buffer overflow (CVE-ID: CVE-2026-20889)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the x3f_thumb_loader functionality. A remote attacker can pass specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Heap-based buffer overflow (CVE-ID: CVE-2026-21413)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the lossless_jpeg_load_raw functionality. A remote attacker can pass specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Integer overflow (CVE-ID: CVE-2026-24450)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the uncompressed_fp_dng_load_raw functionality. A remote attacker can pass specially crafted file, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Heap-based buffer overflow (CVE-ID: CVE-2026-24660)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the x3f_load_huffman functionality. A remote attacker can pass specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
