However, execution of `MultiDecoder::read()` could be interrupted by a panic in caller-supplied `Read` implementation. This would cause `drop()` to be called on uninitialized memory of a generic type implementing `Read`.\n\nThis is equivalent to a use-after-free vulnerability and could allow an attacker to gain arbitrary code execution.\n\nThe flaw was corrected by aborting immediately instead of unwinding the stack in case of panic within `MultiDecoder::read()`. The issue was discovered and fixed by Shnatsel.","status":"published","published":"2019-07-04T12:00:00Z","modified":"2023-11-08T04:01:14.223693Z","cvss":[{"version":"3.0","score":9.8,"vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"critical"}],"updated_at":"2026-11-02T15:53:39.492624Z"},{"id":"UBUNTU-CVE-2019-15552","description":"An issue was discovered in the libflate crate before 0.1.25 for Rust.
