-------------------------------------------------------------------------------- BUGTRAQ ID: 5984 Linux Kernel是開放源代碼的Linux內核系統。 RedHat報告Linux 2.2內核中存在多個問題，本地攻擊者可以利用這些漏洞進行權限提升攻擊。 Linux 2.2內核中存在多個漏洞可導致權限提升，這些漏洞相關與信號處理，數學緩沖區溢出和多播錯誤。目前沒有詳細的漏洞細節描述。 建議： -------------------------------------------------------------------------------- 廠商補丁： RedHat ------ RedHat已經為此發布了一個安全公告（RHSA-2002:210-06）以及相應補丁: RHSA-2002:210-06：New kernel 2.2 packages fix local vulnerabilities 鏈接：https://www.redhat.com/support/errata/RHSA-2002-210.html 在采用這個更新之前，確定所有以前發行的勘誤表中相關補丁已經采用。 手工升級內核過程文檔可從如下地址獲得： http://www.redhat.com/support/docs/howto/kernel-upgrade/ 在升級內核之前請仔細閱讀你結構相關的操作指南。 用戶也可以通過如下RedHat升級代碼通過網絡進行升級： up2date 這個命令將會啟動交互進程安裝升級相關RPM。 補丁下載：
