Description:
Paul Starzetz has reported a vulnerability in the Linux kernel, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a signedness error in the Linux ELF binary format loader's core dump function (elf_core_dump()) and can be exploited to cause a buffer overflow via a specially crafted ELF binary.
Successful exploitation makes it possible to gain root privileges and execute arbitrary code with kernel privileges.
The vulnerability has been reported in versions 2.2 through 2.2.27-rc2, versions 2.4 through 2.4.31-pre1, and versions 2.6 through 2.6.12-rc4.
