Ubuntu 16.04 LTS : Linux kernel (Raspberry Pi 2) vulnerability (USN-3332-1)

The remote Ubuntu 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-3332-1 advisory. It was discovered that the stack guard page for processes in the Linux kernel was not sufficiently large enough to prevent overlapping with the heap. An attacker...

SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2017:1617-1) (Stack Clash)

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-1000364: The default stack guard page was too small and could be 'jumped over' by userland programs using more than one page of stack in functions and ...

kernel: heap/stack gap jumping via unbounded stack allocations

A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap or different memory region and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process sta...

CVE-2017-1000364

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 "jumped" over the stack guard page is bypassed, this affects Linux Kernel versions 4.11.5 and earlier the stackguard page was introduced in 2010...

Design/Logic Flaw

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...
