Source: NVD

Description

NASM contains a heap use after free vulnerability in response file (-@) processing where a dangling pointer to freed memory is stored in the global depend_file and later dereferenced, as the response-file buffer is freed before the pointer is used, allowing for data corruption or remote code execution.

Affected (1)

Products: Nasm: Netwide Assembler

1 product

Netwide Assembler

Configuration A

1 vulnerable

Vulnerable Software	Affected Versions
Nasm Netwide Assembler	Version 3.02 rc5

Related CWEs

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
