GLSA-200501-38 : Perl: rmtree and DBI tmpfile vulnerabilities
Low Nessus Plugin ID 16429
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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 (CAN-2005-0077). Paul Szabo found out that 'File::Path::rmtree' is vulnerable to various race conditions (CAN-2004-0452, CAN-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 functions.
There are no known workarounds at this time.
SolutionAll 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
