Description Laura Pardo 2019-08-01 23:06:53 UTC 
The Rust Programming Language Standard Library 1.18.0 and later is affected by an Information Exposure vulnerability. Contents of uninitialized memory could be printed to string or to log file in the debug trait implementation for std::collections::vec_deque::Iter when the program invokes the debug printing for an iterator over an empty VecDeque.

Comment 1 Laura Pardo 2019-08-01 23:28:58 UTC 
Created rust tracking bugs for this issue:

Affects: epel-7 [bug 1736771]
Affects: fedora-29 [bug 1736769]
Affects: fedora-30 [bug 1736770]
Comment 2 Josh Stone 2019-08-02 16:01:19 UTC 
> 1.18.0 and later

The upstream patch was merged for 1.30.0, so only 1.18.0 through 1.29.* are affected. Fedora and EPEL all have Rust 1.36, so I will close those bugs as CURRENTRELEASE.
Comment 3 Product Security DevOps Team 2019-08-05 01:18:22 UTC
