Vulnerability from csaf_redhat - Published: 2003-09-22 08:46 - Updated: 2024-11-21 22:49
Summary
Red Hat Security Advisory: perl security update
Severity
Important
Notes
Topic: Updated Perl packages that fix a security issue in Safe.pm and a cross-site scripting (XSS) vulnerability in CGI.pm are now available.
Details: Perl is a high-level programming language commonly used for system administration utilities and Web programming. Two security issues have been found in Perl that affect the Perl packages shipped with Red Hat Enterprise Linux: When safe.pm versions 2.0.7 and earlier are used with Perl 5.8.0 and earlier, it is possible for an attacker to break out of safe compartments within Safe::reval and Safe::rdo by using a redefined @_ variable. This is due to the fact that the redefined @_ variable is not reset between successive calls. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-1323 to this issue. A cross-site scripting vulnerability was discovered in the start_form() function of CGI.pm. The vulnerability allows a remote attacker to insert a Web script via a URL fed into the form's action parameter. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0615 to this issue. Users of Perl are advised to upgrade to these erratum packages, which contain Perl 5.6.1 with backported security patches correcting these issues.

Safe.pm 2.0.7 and earlier, when used in Perl 5.8.0 and earlier, may allow attackers to break out of safe compartments in (1) Safe::reval or (2) Safe::rdo using a redefined @_ variable, which is not reset between successive calls.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
