GHSA-9783-42PM-X5JQ

Vulnerability from github – Published: 2022-01-06 22:13 – Updated: 2023-06-13 17:22

Summary

Use of Uninitialized Resource in csv-sniffer.

Details

Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation (within fn preamble_skipcount()).

Arbitrary Read implementations can read from the uninitialized buffer (memory exposure) and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory produces undefined values that can quickly invoke undefined behavior.

Severity ?

9.8 (Critical)

Vulnerability from osv_rustsec

Published

Summary

`Read` on uninitialized memory may cause UB (fn preamble_skipcount())

Details

Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation (within fn preamble_skipcount()).

Arbitrary Read implementations can read from the uninitialized buffer (memory exposure) and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory produces undefined values that can quickly invoke undefined behavior.
