Moderate: rust-toolset:rhel8 security, bug fix, and enhancement update






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)
