Perl PERLIO_DEBUG environment variable file overwrite
| perl-perliodebug-file-overwrite (19207) |  Medium Risk |
Description:
Perl (Practical Extraction and Reporting Language) could allow a remote attacker to overwrite arbitrary files, caused by a vulnerability in the handling of the debug message in the PERLIO_DEBUG environment variable. When Perl is installed with setuid support (sperl), a local attacker could modify the PERLIO_DEBUG environment variable to overwrite arbitrary files on the system.
Consequences:
File Manipulation
Remedy:
For Ubuntu Linux:
Upgrade to the latest perl package (5.8.4-2ubuntu0.3 or later), as listed in USN-72-1 February 02, 2005. See References.
For Red Hat Linux:
Refer to RHSA-2005:103-04 or RHSA-2005:105-11 for patch, upgrade, or suggested workaround information. See References.
For Gentoo Linux:
Refer to Gentoo Linux Security Announcement GLSA 2005-02-13 for patch, upgrade, or suggested workaround information. See References.
