CVE-2009-2909

CVE-2009-2909 affects the Linux kernel ax25 subsystem (ax25_setsockopt in net/ax25/af_ax25.c). The vulnerability arises from a signedness/unsigned check issue in the ax25 sockopt/setsockopt path, enabling a local attacker to cause a kernel OOPS or potentially crash the kernel and execute code. Pu...

Linux Kernel 'net/ax25/af_ax25.c'本地拒绝服务漏洞

Bugraq ID: 36635 Linux是一款开放源代码的操作系统。 Linux不正确校验用户值的符号正负，本地攻击者可以利用漏洞使内核崩溃。 ax25代码尝试使用： if optlen sizeofint return -EINVAL; 对设置套接字选项中的optlen是否会负（或零）做安全检查。 不幸的是"sizeofint"是一个无符号属性，结果可导致整个比较在无符号的情况下完成，是的负值可绕过检查。 Linux kernel 2.6.31 -rc7 Linux kernel 2.6.31 -rc6 Linux kernel 2.6.31 -rc3 + Trustix Secu...
