漏洞描述
中文描述:
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。 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。
英文描述:
In iconvdata/iso-2022-jp-3.c in the GNU C Library (aka glibc) 2.34, remote attackers can force iconv() to emit a spurious '\0' character via crafted ISO-2022-JP-3 data that is accompanied by an internal state reset. This may affect data integrity in certain iconv() use cases. NOTE: the vendor states "the bug cannot be invoked through user input and requires iconv to be invoked with a NULL inbuf, which ought to require a separate application bug to do so unintentionally. Hence there's no security impact to the bug.
