According to the versions of the glibc packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when     processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in     degraded service or Denial of Service on the local system. This is related to netgroupcache.c.
    (CVE-2021-27645)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2021:4358 advisory.

  - The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when     processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in     degraded service or Denial of Service on the local system. This is related to netgroupcache.c.
    (CVE-2021-27645)

  - The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It     may use the notification thread attributes object (passed through its struct sigevent parameter) after it     has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified     other impact. (CVE-2021-33574)

  - The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in     parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in     a denial of service or disclosure of information. This occurs because atoi was used but strtoul should     have been used to ensure correct calculations. (CVE-2021-35942)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2021:4358 advisory.

  - The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in     parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in     a denial of service or disclosure of information. This occurs because atoi was used but strtoul should     have been used to ensure correct calculations. (CVE-2021-35942)

The remote NewStart CGSL host, running version MAIN 6.02, has glibc packages installed that are affected by multiple vulnerabilities:

  - The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple     suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite     loop when processing invalid multi-byte input sequences, leading to a denial of service. (CVE-2016-10228)

  - The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-     byte input sequences in the EUC-KR encoding, may have a buffer over-read. (CVE-2019-25013)

  - The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid     multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance     the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a     different vulnerability from CVE-2016-10228. (CVE-2020-27618)

  - The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when     processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in     degraded service or Denial of Service on the local system. This is related to netgroupcache.c.
    (CVE-2021-27645)

  - The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid     input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program,     potentially resulting in a denial of service. (CVE-2021-3326)

  - The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It     may use the notification thread attributes object (passed through its struct sigevent parameter) after it     has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified     other impact. (CVE-2021-33574)

  - A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory     corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and     size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and     escalate their privileges on the system. (CVE-2021-3999)

  - The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc)     through 2.34 copies its path 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. (CVE-2022-23218)

  - 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. (CVE-2022-23219)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
