Debian DLA-2273-1 : shiro security update

critical Nessus Plugin ID 138224

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was two issues in shiro, a security framework for Java application :

- CVE-2020-1957: Fix a path-traversal issue where a specially crafted request could cause an authentication bypass.

- CVE-2020-11989: Fix an encoding issue introduced in the handling of the previous CVE-2020-1957 path-traversal issue which itself could have also caused an authentication bypass.

For Debian 9 'Stretch', these issues have been fixed in shiro version 1.3.2-1+deb9u1.

We recommend that you upgrade your shiro packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected libshiro-java package.
