NetBSD Larn 'Games'组本地特权提升漏洞

Bugtraq ID: 44293 NetBSD是一款基于BSD的操作系统。 当game从setuid更改为setgid时larn没有进行更新-把用户IDs替代为组IDs，这意味着当试图下降到低特权级别时，没有任何事情发生。因此game一直以game组权限运行，并可以games组权限进行各种如写或保存文件操作。 保存文件可写入/var/games可覆盖或破坏属于其他游戏的文件。 NetBSD 4.0 厂商解决方案 已经修补的源文件可从NetBSD CVS库中获得： CVS branch file revision ------------- ----------------...

NetBSD 'SMBIOC_OPENSESSION' IOCTL本地拒绝服务漏洞

Bugtraq ID: 44288 NetBSD是一款基于BSD的操作系统。 netsmb文件系统内核模块不正确检查缓冲区限制，普通用户可使内核分配过大的内部缓冲区去处理请求，导致内存耗竭。 ioctl SMBIOCOPENSESSION中的长度参数为有符号类型，没有检查负值。 NetBSD 5.0.2 NetBSD 4.0.1 NetBSD 5.0 NetBSD 4.0 厂商解决方案 已经修补的源文件可从NetBSD CVS库中获得： CVS branch file revision ------------- ---------------- ----------- HEAD...
