1) Stack-based buffer overflow (CVE-ID: CVE-2018-10753)

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

The vulnerability exists due to a boundary error within the delayed_output() function in music.c in abcm2ps. A remote attacker can trick the victim to open a specially crafted file with the application, trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Stack-based buffer overflow (CVE-ID: CVE-2018-10771)

The vulnerability exists due to a boundary error within the get_key function() in parse.c in abcm2ps. A remote attacker can create a specially crafted file, trick the victim into opening it with the affected version of application, trigger stack-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) Input validation error (CVE-ID: CVE-2019-1010069)
