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).
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
There are no known workarounds at this time.
All Perl users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-lang/perl
All DBI library users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-perl/DBI
