Summary
nasm security update
Details
NASM is the Netwide Assembler, a free portable assembler for the Intel 80x86 microprocessor series, using primarily the traditional Intel instruction mnemonics and syntax. It also provides tools in RDOFF binary format, includes linker, library manager, loader, and information dump.\r\n\r\n Security Fix(es):\r\n\r\n In Netwide Assembler (NASM) 2.15rc0, a heap-based buffer over-read occurs (via a crafted .asm file) in set_text_free when called from expand_one_smacro in asm/preproc.c.(CVE-2019-20352)\r\n\r\n In Netwide Assembler (NASM) 2.15rc10, there is heap use-after-free in saa_wbytes in nasmlib/saa.c.(CVE-2020-24241)\r\n\r\n

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
