The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2021:3063 advisory.
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)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
