Out-of-bounds
A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this...
kernel: userspace applications can misuse the KVM API to cause a write of 16 bytes at an offset up to 32 GB from vcpu->run
A flaw was found in the Linux kernel. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability...

golang: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs
A flaw was found in the Go encoding/binary package. Certain invalid inputs to the ReadUvarint or the ReadVarint causes those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This flaw possibly leads to processing more input than expected. The...

Denial of Service (DoS)
Overview @nubosoftware/node-static is a simple, compliant file streaming module for node Affected versions of this package are vulnerable to Denial of Service DoS. The package fails to catch an exception when user input includes null bytes. This allows attackers to access http://host/%00 and cras...

Rust is vulnerable to denial of service. The optimization for joining strings can cause uninitialized bytes to be exposed or lead to an application crash...
Mozilla Rust Formatting String Error Vulnerability
Rust is a general-purpose, compiled programming language from the Mozilla Foundation. A format string error vulnerability exists in the standard library in versions of Rust prior to 1.52.0, which stems from the fact that if the length of a borrowed string is changed after checking it, it could...
Archives may contain uninitialized memory
rkyv is a serialization framework that writes struct-compatible memory to be stored or transmitted. During serialization, struct padding bytes and unused enum bytes may not be initialized. These bytes may be written to disk or sent over unsecured channels...
In the standard library in Rust before 1.52.0 there is an optimization for joining strings that can cause uninitialized bytes to be exposed (or the program to crash) if the borrowed string changes after its length is checked.
