GHSA-955P-RC5H-HG6H

Vulnerability from github – Published: 2021-08-25 20:55 – Updated: 2023-06-13 16:52
VLAI?
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)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
