RHEL 6 : kernel (RHSA-2017:2798)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2798 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: A flaw was found in the way the Linux kernel...

kernel: load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary

A flaw was found in the way the Linux kernel loaded ELF executables. Provided that an application was built as Position Independent Executable PIE, the loader could allow part of that application's data segment to map over the memory area reserved for its stack, potentially resulting in memory...

Important: Red Hat Security Advisory: kernel security update

An update for kernel is now available for Red Hat Enterprise Linux 7.2 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...

kernel: Incorrectly mapped contents of PIE executable

The Linux Kernel running on AMD64 systems will sometimes map the contents of PIE executable, the heap or ld.so to where the stack is mapped allowing attackers to more easily manipulate the stack. Linux Kernel version 4.11.5 is affected...

Amazon Linux AMI : kernel (ALAS-2017-845) (Stack Clash)

An issue was discovered in the size of the stack guard page on Linux, specifically a 4k stack guard page is not sufficiently large and can be jmp'ed over, this affects Linux Kernel versions 4.11.5 and earlier the stackguard page was introduced in 2010. CVE-2017-1000364 The offset2lib patch as use...

CVE-2017-1000371

The offset2lib patch as used by the Linux Kernel contains a vulnerability, if RLIMITSTACK is set to RLIMINFINITY and 1 Gigabyte of memory is allocated the maximum under the 1/4 restriction then the stack will be grown down to 0x80000000, and as the PIE binary is mapped above 0x80000000 the minimu...

CVE-2017-1000370

The offset2lib patch as used in the Linux Kernel contains a vulnerability that allows a PIE binary to be execve'ed with 1GB of arguments or environmental strings then the stack occupies the address 0x80000000 and the PIE binary is mapped above 0x40000000 nullifying the protection of the offset2li...
