- (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" also handles temporary files
- insecurely (CAN-2004-0452).
-
- 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 files with the rights of the user calling these functions.
-
- Workaround
-
- There are no known workarounds at this time.

-
- Solution:
- 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

- Risk factor : Medium
