CVE-2022-39831
There is a heap-based buffer overflow at the function read_bytes_internal in utilities/pspp-dump-sav.c, which allows attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.52%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
