Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2019-19887)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in jfif_encode() function. A remote attacker can perform a denial of service (DoS) attack via a specially crafted file.


2) Division by zero (CVE-ID: CVE-2019-19888)

The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to divide-by-zero error within the jfif_decode() function in jfif.c. A remote attacker can pass a specially crafted file to the application and perform a denial of service attack.


3) NULL pointer dereference (CVE-ID: CVE-2019-16350)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in idct2d8x8() at dct.c. A remote attacker can perform a denial of service (DoS) attack.


4) NULL pointer dereference (CVE-ID: CVE-2019-16351)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in huffman_decode_step() at huffman.c. A remote attacker can perform a denial of service (DoS) attack.


5) Heap-based buffer overflow (CVE-ID: CVE-2019-16352)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the jfif_load() at jfif.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger 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.


6) Input validation error (CVE-ID: CVE-2018-16781)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input when processing JPEG files that lack an AC Huffman table. A remote attacker can pass specially crafted file to the application and perform a denial of service (DoS) attack.
