Name of the Vulnerable Software and Affected Versions: nasm versions 2.14.01rc5 through 2.15

Description: The issue is related to a Buffer Overflow in the asm/stdscan.c file at line 130, which can cause a stack-overflow due to endless macro generation when triggered by a crafted nasm input file, leading to a program crash.

Recommendations: For nasm versions 2.14.01rc5 through 2.15, consider disabling the macro generation feature as a temporary workaround until a patch is available. Restrict access to the asm/stdscan.c file to minimize the risk of exploitation. Avoid using crafted nasm input files that can trigger the endless macro generation.
