Debian DLA-3669-1 : cryptojs - LTS security update

critical Nessus Plugin ID 186304

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has a package installed that is affected by a vulnerability as referenced in the dla-3669 advisory.

- crypto-js is a JavaScript library of crypto standards. Prior to version 4.2.0, crypto-js PBKDF2 is 1,000 times weaker than originally specified in 1993, and at least 1,300,000 times weaker than current industry standard. This is because it both defaults to SHA1, a cryptographic hash algorithm considered insecure since at least 2005, and defaults to one single iteration, a 'strength' or 'difficulty' value specified at 1,000 when specified in 1993. PBKDF2 relies on iteration count as a countermeasure to preimage and collision attacks. If used to protect passwords, the impact is high. If used to generate signatures, the impact is high. Version 4.2.0 contains a patch for this issue. As a workaround, configure crypto-js to use SHA256 with at least 250,000 iterations. (CVE-2023-46233)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the cryptojs packages.

For Debian 10 buster, this problem has been fixed in version 3.1.2+dfsg-2+deb10u1.
