[Bug 1961117] Re: Vulnerability in glibc - CVE-2022-23219

[Steve Beattie]

This issue was addressed in Ubuntu in
https://ubuntu.com/security/notices/USN-5310-1 and
https://ubuntu.com/security/notices/USN-5310-2 and the under development
jammy/Ubuntu 22.04 LTS already has glibc 2.35 incorporated.

Please also note that Ubuntu has been building with stack-protector
enabled since 2006, and thus the issue was limited to a denial of
service.

Thanks.

** Changed in: glibc (Ubuntu)

Bug description:
  Title: Vulnerability in Glibc - CVE-2022-23219
   
  Expectation: Glibc needs to be upgraded to glib v2.35 (Feb2022 release) 
   
  Details of CVE - https://nvd.nist.gov/vuln/detail/CVE-2022-23219 & https://ubuntu.com/security/CVE-2022-23219
   
  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.
