2023-11-02漏洞描述
In versions of FreeBSD 12.4-RELEASE prior to 12.4-RELEASE-p7 and FreeBSD 13.2-RELEASE prior to 13.2-RELEASE-p5 the __sflush() stdio function in libc does not correctly update FILE objects write space members for write-buffered streams when the write(2) system call returns an error. Depending on the nature of an application that calls libcs stdio functions and the presence of errors returned from the write(2) system call (or an overridden stdio write routine) a heap buffer overflow may occur. Such overflows may lead to data corruption or the execution of arbitrary code at the privilege level of the calling program.解决建议
建议您更新当前系统或软件至最新版，完成漏洞的修复。
