RUSTSEC-2021-0015 (CVE-2021-26951)

Vulnerability from osv_rustsec – Published: 2021-01-06 12:00 – Updated: 2023-06-13 13:10 – Source website

Summary

`Sectors::get` accesses unclaimed/uninitialized memory

Details

Affected versions of this crate arbitrarily calls Vec::set_len to increase length of a vector without claiming more memory for the vector. Affected versions of this crate also calls user-provided Read on the uninitialized memory of the vector that was extended with Vec::set_len.

This can overwrite active entities in adjacent heap memory and seems to be a major security issue. Also, calling user-provided Read on uninitialized memory is defined as UB in Rust.

Severity

9.8 (Critical)

CVE-2021-26951 (GCVE-0-2021-26951)

Vulnerability from cvelistv5 – Published: 2021-02-09 22:07 – Updated: 2024-08-03 20:33

Summary

An issue was discovered in the calamine crate before 0.17.0 for Rust. It allows attackers to overwrite heap-memory locations because Vec::set_len is used without proper memory claiming, and this uninitialized memory is used for a user-provided Read operation, as demonstrated by Sectors::get.

Severity

No CVSS data available.
