Linux Kernel 'offset2lib' Local Security Bypass Vulnerability

Linux kernel is an open source operating system. A local security bypass vulnerability exists in Linux Kernel 'offset2lib', which allows local attackers to exploit the vulnerability to submit special requests and bypass restrictions...

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...

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...

DEBIAN-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...

CVE-2017-1000370

CVE-2017-1000370 affects the Linux kernel (4.11.5 and earlier) on i386. The offset2lib patch vulnerability lets a PIE binary be execve’d with an enormous 1 GB argument/environment list, causing the stack to occupy 0x80000000 and the PIE binary to be mapped above 0x40000000, bypassing the patch’s ...

CVE-2017-1000371

CVE-2017-1000371 is a Linux kernel vulnerability reported for the 4.11.5 release, caused by the offset2lib patch that can allow a stack/heap clash for 32-bit PIE binaries when RLIMIT_STACK is RLIMIT_INFINITY and 1 GB is allocated. Consequences include potential local impact (stack guard page bypa...
