Arch Linux Security Advisory ASA-201901-16 ========================================== Severity: Medium Date : 2019-01-24 CVE-ID : CVE-2019-6290 CVE-2019-6291 Package : nasm Type : denial of service Remote : No Link : https://security.archlinux.org/AVG-852 Summary ======= The package nasm before version 2.14.02-1 is vulnerable to denial of service. Resolution ========== Upgrade to 2.14.02-1. # pacman -Syu "nasm>=2.14.02-1" The problems have been fixed upstream in version 2.14.02. Workaround ========== None. Description =========== - CVE-2019-6290 (denial of service) An infinite recursion issue was discovered in eval.c in Netwide Assembler (NASM) through 2.14.02. There is a stack exhaustion problem resulting from infinite recursion in the functions expr, rexp, bexpr and cexpr in certain scenarios involving lots of '{' characters. Remote attackers could leverage this vulnerability to cause a denial-of- service via a crafted asm file. - CVE-2019-6291 (denial of service) An issue was discovered in the function expr6 in eval.c in Netwide Assembler (NASM) through 2.14.02. There is a stack exhaustion problem caused by the expr6 function making recursive calls to itself in certain scenarios involving lots of '!' or '+' or '-' characters. Remote attackers could leverage this vulnerability to cause a denial- of-service via a crafted asm file. Impact ====== A local attacker is able to cause a denial of service via a specially crafted asm file.
