CVE-2021-41771: Buffer Overflow
First published: Thu Oct 14 2021(Updated: )
An out of bounds read vulnerability was found in debug/macho of the Go standard library. When using the debug/macho standard library (stdlib) and malformed binaries are parsed using Open or OpenFat, it can cause golang to attempt to read outside of a slice (array) causing a panic when calling ImportedSymbols. An attacker can use this vulnerability to craft a file which causes an application using this library to crash resulting in a denial of service.
