CVE-ID : CVE-2019-6290 CVE-2019-6291
Package : nasm
Type : denial of service
Remote : No
Link : https://security.archlinux.org/AVG-852
The package nasm before version 2.14.02-1 is vulnerable to denial of
service.
Upgrade to 2.14.02-1.
The problems have been fixed upstream in version 2.14.02.
None.
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.
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.
A local attacker is able to cause a denial of service via a specially
crafted asm file.
