CVE number – CVE-2019-13626
A vulnerability in Simple DirectMedia Layer (SDL) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a targeted system.
The vulnerability is due to an integer overflow condition that exists in the IMA_ADPCM_decode()function, as defined in the audio/SDL_wave.c source code file of the affected software. An attacker could exploit this vulnerability by persuading a user to access a file that submits malicious input to the targeted system. A successful exploit could trigger a heap-based buffer over-read condition in the Fill_IMA_ADPCM_block function, resulting in a DoS condition. Proof-of-concept (PoC) code that demonstrates an exploit of this vulnerability is publicly available. The vendor has confirmed the vulnerability; however, software updates are not available.
- To exploit this vulnerability, an attacker may use misleading language or instructions to persuade a user to access a file that submits malicious input to the targeted system.
