CVE-2022-23219

Public on 2022-01-14
Modified on 2024-01-30
Description

A stack based buffer-overflow vulnerability was found in the deprecated compatibility function clnt_create() in the sunrpc's clnt_gen.c module of the GNU C Library (aka glibc) through 2.34. This vulnerability copies its hostname argument onto the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) lead to arbitrary code execution.
