[GLSA-200501-38] Perl: rmtree and DBI tmpfile vulnerabilities |
||
Perl: rmtree and DBI tmpfile vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200501-38 (Perl: rmtree and DBI tmpfile vulnerabilities) Javier Fernandez-Sanguino Pena discovered that the DBI library creates temporary files in an insecure, predictable way (CVE-2005-0077). Paul Szabo found out that "File::Path::rmtree" is vulnerable to various race conditions (CVE-2004-0452, CVE-2005-0448). Impact A local attacker could create symbolic links in the temporary files directory that point to a valid file somewhere on the filesystem. When the DBI library or File::Path::rmtree is executed, this could be used to overwrite or remove files with the rights of the user calling these functions. Workaround There are no known workarounds at this time.
