In radare2 through 5.3.0 there is a double free vulnerability in the pyc parse via a crafted file which can lead to DoS.

An issue was discovered in the algorithmica crate through 2021-03-07 for Rust. There is a double free in merge_sort::merge().

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit Reader 10.1.1.37576. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of U3D objects embedded in PDF files. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-13280.

An issue was discovered in the slice-deque crate through 2021-02-19 for Rust. A double drop can occur in SliceDeque::drain_filter upon a panic in a predicate function.

An issue was discovered in the insert_many crate through 2021-01-26 for Rust. Elements may be dropped twice if a .next() method panics.

An issue was discovered in the arenavec crate through 2021-01-12 for Rust. A double drop can sometimes occur upon a panic in T::drop().

In FreeBSD 13.0-STABLE before n245050, 12.2-STABLE before r369525, 13.0-RC4 before p0, and 12.2-RELEASE before p6, listening socket accept filters implementing the accf_create callback incorrectly freed a process supplied argument string. Additional operations on the socket can lead to a double free or use after free.
