RUSTSEC-2021-0040 (CVE-2021-29930)

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

Summary

panic safety: double drop or uninitialized drop of T upon panic

Details

Affected versions of this crate did not guard against potential panics that may happen from user-provided functions T::default() and T::drop().

Panic within T::default() leads to dropping uninitialized T, when it is invoked from common::Slice::<T, H>::new(). Panic within T::drop() leads to double drop of T, when it is invoked either from common::SliceVec::<T, H>::resize_with() or common::SliceVec::<T, H>::resize()

Either case causes memory corruption in the heap memory.

Severity

7.5 (High)

GHSA-955P-RC5H-HG6H

Vulnerability from github – Published: 2021-08-25 20:55 – Updated: 2023-06-13 16:52

Summary

Double free in arenavec

Details

Affected versions of this crate did not guard against potential panics that may happen from user-provided functions T::default() and T::drop().

Panic within T::default() leads to dropping uninitialized T, when it is invoked from common::Slice::::new(). Panic within T::drop() leads to double drop of T, when it is invoked either from common::SliceVec::::resize_with() or common::SliceVec::::resize()

Either case causes memory corruption in the heap memory.

Severity

7.5 (High)
