NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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. NOTE: there may be limited scenarios in which this issue is relevant.
