Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2019-2201)

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

The vulnerability exists due to integer overflow in tjbench.c when handling JPEG images. A remote attacker can create a specially crafted JPEG image, pass it to the affected application, 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-2018-20330)

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

The vulnerability exists due to a boundary error within the tjLoadImage() function in libjpeg-turbo 2.0.1. A remote attacker can 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) Out-of-bounds read (CVE-ID: CVE-2018-19664)

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

The vulnerability exists due to heap-based buffer over-read in the put_pixel_rows() function in wrbmp.c, as demonstrated by djpeg. A remote attacker can perform a denial of service attack.


4) Out-of-bounds read (CVE-ID: CVE-2018-14498)

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

The vulnerability exists due to a boundary condition when processing a crafted 8-bit BMP in which one or more of the color indices is out of range for the number of palette entries within the get_8bit_row in rdbmp.c. A remote attacker can create a specially crafted file, pass it to the application, trigger out-of-bounds read error and crash the affected application.
