CVE-ID: CVE-2019-19647

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  r_asm_pseudo_incbin(0 function at libr/asm/asm.c. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
