CVE-2011-5000
The ssh_gssapi_parse_ename function in gss-serv.c in OpenSSH 5.8 and earlier, when gssapi-with-mic authentication is enabled, allows remote authenticated users to cause a denial of service (memory consumption) via a large value in a certain length field.
Does this matter?
Lower severity and a low EPSS score (2.56%). Track it; it rarely justifies an emergency change on its own.
