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

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.
