| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux Kernel versions prior to 3.10.77
Description
The issue is related to the function
load elf binary() in the Linux kernel, which incorrectly allocates address space for PIE binaries when CONFIG ARCH BINFMT ELF RANDOMIZE PIE is enabled and a normal top-down address allocation strategy is used. This can lead to a stack buffer corruption vulnerability, potentially allowing a local attacker to execute arbitrary code. The vulnerability was fixed in April 2015 but was not recognized as a security threat at the time.Recommendations
For Linux Kernel versions prior to 3.10.77, update to version 3.10.77 or later to resolve the issue. As a temporary workaround, consider disabling the
CONFIG ARCH BINFMT ELF RANDOMIZE PIE configuration option to minimize the risk of exploitation. Restrict access to the load elf binary() function to prevent potential attacks.Exploit
