Amazon Linux 1 Security Advisory: ALAS-2022-1576
Advisory Release Date: 2022-04-04 23:46 Pacific
Advisory Updated Date: 2022-04-06 21:33 Pacific
A stack based buffer-overflow vulnerability was found in the deprecated compatibility function svcunix_create() in the sunrpc's svc_unix.c module of the GNU C Library (aka glibc) through 2.34. This vulnerability copies its path 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) then it will lead to arbitrary code execution. (CVE-2022-23218)
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. (CVE-2022-23219)
