https://nvd.nist.gov/vuln/detail/CVE-2023-31975 is freaking out scanners since it claims this bug has a CVSS of 9.8. From what I see at https://github.com/yasm/yasm/issues/210 though, I can't see any CVSS higher than 0.0 being relevant here and think the CVE should be withdrawn. Am I missing something here? All I see is 2 objects of 16 bytes each not being freed in the fraction of a second before the command exits and automatically frees the memory - in a command the user deliberately chooses to run, which runs as themselves with no raised privileges, on an input file they provide, and which exits after processing the file and doesn't hang around keeping that memory allocated - not a bit of security risk at all there. (Yes, it's a small bug and is good to fix, but not to raise security alarms for.) -- -Alan Coopersmith- alan.coopersmith () oracle com Oracle Solaris Engineering - https://blogs.oracle.com/solaris
I don’t think you are, I can’t see anything here either. Even if you were doing all the wrong things and running a yasm-as-a-service continually building untrusted source right alongside other processes as the same user, that contain all sorts of things you don’t want exposed, I still don’t see how this would be anything but a 0.0.
