Description:

The remote host is affected by the vulnerability described in GLSA-200410-24
(MIT krb5: Insecure temporary file use in send-pr.sh)


The send-pr.sh script creates temporary files in world-writeable
directories with predictable names.

Impact

A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When
send-pr.sh is called, this would result in the file being overwritten with
the rights of the user running the utility, which could be the root user.

Workaround

There is no known workaround at this time.
