The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:3063 advisory.

Rust Toolset provides the Rust programming language compiler rustc, the cargo build tool and dependency     manager, and required libraries.

The following packages have been upgraded to a later upstream version: rust (1.52.1). (BZ#1953002)

Security Fix(es):

* rust: optimization for joining strings can cause uninitialized bytes to be exposed (CVE-2020-36323)

* rust: heap-based buffer overflow in read_to_end() because it does not validate the return value from     Read in an unsafe context (CVE-2021-28875)

* rust: panic safety issue in Zip implementation (CVE-2021-28876)

* rust: memory safety violation in Zip implementation for nested iter::Zips (CVE-2021-28877)

* rust: memory safety violation in Zip implementation when next_back() and next() are used together     (CVE-2021-28878)

* rust: integer overflow in the Zip implementation can lead to a buffer overflow (CVE-2021-28879)

* rust: double free in Vec::from_iter function if freeing the element panics (CVE-2021-31162)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

For information on usage, see Using Rust Toolset linked in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
