CVE:CVE-2021-43396
CNNVD:CNNVD-202111-457
GNU C Library（glibc，libc6）是一种按照LGPL许可协议发布的开源免费的C语言编译程序。glibc（GNU C Library）是GNU计划所实现的C标准库。
GNU C Library (又名 glibc) 2.34版本存在安全漏洞，该漏洞源于受影响版本库中iconvdata/iso-2022-jp-3.c的iconv()存在数据校验问题。远程攻击者可利用该漏洞通过精心制作的ISO-2022-JP-3数据强制iconv()发出一个虚假的0字符，并伴随着内部状态重置。在某些iconv()用例中，这可能会影响数据完整性。
solution:Upgrade gnu glibc to a higher version than 2.34,and avoid the version 2.34; Upgrade oracle communications_cloud_native_core_binding_support_function to a higher version than 22.1.3,and avoid the version 22.1.3; Upgrade oracle communications_cloud_native_core_network_function_cloud_native_environment to a higher version than 22.1.0,and avoid the version 22.1.0; Upgrade oracle communications_cloud_native_core_network_repository_function to a higher version than 22.1.2,22.2.0,and avoid the version 22.1.2,22.2.0; Upgrade oracle communications_cloud_native_core_security_edge_protection_proxy to a higher version than 22.1.1,and avoid the version 22.1.1; Upgrade oracle communications_cloud_native_core_unified_data_repository to a higher version than 22.2.0,and avoid the version 22.2.0; Upgrade oracle enterprise_operations_monitor to a higher version than 4.3,4.4,5.0,and avoid the version 4.3,4.4,5.0
