CVE-2019-1010299 : Exploit Details and Defense Strategies
Learn about CVE-2019-1010299 affecting Rust Programming Language Standard Library versions 1.18.0 and later. Find out how to mitigate the information exposure vulnerability and prevent risks.
The Rust Programming Language Standard Library version 1.18.0 and later is susceptible to CWE-200, which is the exposure of information. This vulnerability can result in the printing of uninitialized memory to a string or log file. The specific component affected is the Debug trait implementation for std::collections::vec_deque::Iter. To exploit this vulnerability, the program must invoke debug printing for an iterator over an empty VecDeque. This issue has been resolved in version 1.30.0, as well as in nightly versions after commit b85e4cc8fadaabd41da5b9645c08c68b8f89908d.
