Name of the Vulnerable Software and Affected Versions nasm versions prior to 2.15.05

Description The issue is related to a buffer overflow vulnerability in the quote for pmake function in asm/nasm.c of the Netwide Assembler (NASM). This vulnerability can be exploited by attackers to cause a denial of service via crafted files. The vulnerability is associated with the lack of size checking for input data, allowing for uncontrolled copying into a buffer.

Recommendations For versions prior to 2.15.05, update to version 2.15.05 or later to resolve the issue. As a temporary workaround, consider restricting the use of the quote for pmake function in asm/nasm.c to minimize the risk of exploitation.
