CVE-2006-6164

The dlunsetenv function in loader.c in the ELF ld.so in OpenBSD 3.9 and 4.0 does not properly remove duplicate environment variables, which allows local users to pass dangerous variables such as LDPRELOAD to loading processes, which might be leveraged to gain privileges...

CVE-2006-6164

The CVE-2006-6164 entry concerns OpenBSD 3.9 and 4.0 where the _dl_unsetenv function in loader.c of the ELF ld.so fails to remove duplicate environment variables. This could allow local users to pass dangerous variables (e.g., LD_PRELOAD) to loading processes, potentially enabling privilege escal...

OpenBSD semaphore分配拒绝服务漏洞

OpenBSD是一款开放源代码Unix类操作系统。 OpenBSD内核实现上存在漏洞，如果本地攻击者分配了多于默认数目的sempahore的话，就会导致内核忙碌。 OpenBSD OpenBSD 3.9 OpenBSD OpenBSD 3.8 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： ftp://ftp.openbsd.org/pub/OpenBSD/patches/3.8/common/012sem.patch ftp://ftp.openbsd.org/pub/OpenBSD/patches/3.9/common/007sem.patch...

OpenBSD ISAKMPD IPsec通信会话回放漏洞

OpenBSD是一款开放源代码Unix类操作系统。 OpenBSD的isakmpd工具在处理通信会话时存在漏洞，远程攻击者可能利用此漏洞执行消息回放攻击。 如果在SA协商期间OpenBSD将isakmpd8用作响应程序的话，则在响应SA协商时isakmpd8就会创建一个大小为0的回放窗口，这样攻击者就可以截获并回放IPSec报文。漏洞的具体影响取决于所回放的网络通讯。 OpenBSD OpenBSD 3.9 OpenBSD OpenBSD 3.8 OpenBSD ------- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载：...

OpenBSD systrace systrace_preprepl本地整数溢出漏洞

OpenBSD是一款开放源代码Unix类操作系统，OpenBSD的systrace功能可以允许或拒绝被管理进程所执行的syscall。 systrace的内核组件中存在整数溢出漏洞，允许攻击者通过在systrace ioctl中指定很大的整数值触发这个漏洞，导致绕过安全检查、向任意内核地址越界写入空字节或读取内核内存块。 漏洞代码在systracepreprepl函数中： for i = 0, len = 0; i repl-strrnrepl; i++ len += repl-strroffleni; if repl-strroffleni == 0 continue; if...
