Vulnerability Assessment Details

[GLSA-200410-24] MIT krb5: Insecure temporary file use in send-pr.sh

Vulnerability Assessment Summary
MIT krb5: Insecure temporary file use in send-pr.sh

Detailed Explanation for this Vulnerability Assessment
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.
