2) Division by zero

EUVDB-ID: #VU17049

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-11212

CWE-ID: CWE-369 - Divide By Zero

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.

3) Input validation error

EUVDB-ID: #VU24196

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-11213

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.

CVE-ID: CVE-2018-14498

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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.
