VUL-0: CVE-2024-26458: krb5: memory leak at /krb5/src/lib/rpc/pmap_rmt.c
Last modified: 2024-07-05 11:15:05 UTC
Kerberos 5 (aka krb5) 1.21.2 contains a memory leak in /krb5/src/lib/rpc/pmap_rmt.c.

The pmap_rmt.c leak only affects pmap_rmtcall(), which is unused by the rest of the krb5 code base and likely unused by anyone else. The k5sealv3.c leak affects an encoding function, and happens on a bounds check which likely cannot be triggered with any choice of memory-valid API inputs. (The bounds check was itself introduced to quash a different static analysis defect.) The ndr.c leak also affects an encoding function, and triggers if the input contains invalid UTF-8. This one might be triggerable by a request (though it may require elevated privilege), but I would not have requested a CVE for it myself. I will fix these on the mainline, but I only expect to assign a ticket to the third one.

As indicated at https://bugzilla.suse.com/show_bug.cgi?id=1221579#c3, point 2, I think 11SP4 is affected, but I see in smash it's still under analysis. Security team, could you confirm 11SP4 is affected?
