[GLSA-200410-07] ed: Insecure temporary file handling

Vulnerability Assessment Summary ed: Insecure temporary file handling Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200410-07 (ed: Insecure temporary file handling) ed insecurely creates temporary files in world-writeable directories with predictable names. Given that ed is used in various system shell scripts, they are by extension affected by the same vulnerability. Impact A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When ed is called, this would result in file access with the rights of the user running the utility, which could be the root user. Workaround There is no known workaround at this time.
