Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2016-3616)

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

The vulnerability exists due to a NULL pointer dereference error within the cjpeg utility in libjpeg. A remote attacker can create a specially crafted image and perform a denial of service (DoS) attack.


2) Division by zero (CVE-ID: CVE-2018-11212)

The vulnerability allows a remote attacker to cause DoS condition.

The weakness exists due to division by zero error within the libjpeg library within the libjpeg-turbo in alloc_sarray() function of jmemmgr.c file. A remote attacker can pass a specially crafted file the to affected application and cause application to crash.

3) Input validation error (CVE-ID: CVE-2018-11213)

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 within the get_text_gray_row() function in rdppm.c. A remote attacker can create a specially crafted image, trick the victim into opening it with software that uses the affected version of libjpeg, and perform a denial of service attack.


4) Input validation error (CVE-ID: CVE-2018-11214)

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 within the get_text_rgb_row() function in rdppm.c. A remote attacker can create a specially crafted image, trick the victim into opening it with software that uses the affected version of libjpeg, and perform a denial of service attack.


5) Infinite loop (CVE-ID: CVE-2018-11813)

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

The vulnerability exists due to infinite loop in read_pixel() function in rdtarga.c when processing EOF (end-of-line) characters. A remote attacker can use a specially crafted image to consume all available system resources and cause denial of service conditions.


6) 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.
