CVE-2022-23219
9.8
CRITICAL · CVSS 3.1 · EPSS 4.3% (pctl 91)
In your normal cycle
Critical by CVSS (9.8), but no sign of active exploitation.
Description
The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its hostname argument on 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) arbitrary code execution.
