    Linux Kernel Denial of Service and IPsec Policy Bypass

    Category Vendors/Products
    Posted By
    Two vulnerabilities have been reported in the Linux kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service) or bypass certain security restrictions.

    1) The "setsockopt()" function is not restricted to privileged users with the "CAP_NET_ADMIN" capability. This can be exploited to bypass IPsec policies or set invalid policies to exploit other vulnerabilities or exhaust available kernel memory.

    2) An error in the "syscall32_setup_pages()" function on 64-bit x86 platforms can be exploited to cause a memory leak by executing a malicious 32-bit application with specially crafted ELF headers.

    1) The vulnerability has been fixed in version 2.6.13-rc7.
    2) The vulnerability has been fixed in version 2.6.13-rc4.
