AlmaLinux 8 : rust-toolset:rhel8 (ALSA-2021:4270)

critical Nessus Plugin ID 157712

Synopsis

The remote AlmaLinux host is missing a security update.

Description

The remote AlmaLinux 8 host has a package installed that is affected by a vulnerability as referenced in the ALSA-2021:4270 advisory.

 - library/std/src/net/parser.rs in Rust before 1.53.0 does not properly consider extraneous zero characters at the beginning of an IP address string, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation. (CVE-2021-29922)

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

Solution

Update the affected rust-toolset package.
