Updated kernel-linus packages fixes critical security vulnerabilities
This kernel-linus update is based on upstream 4.4.74 and fixes at least the following security issues: The ipxitfioctl function in net/ipx/afipx.c in the Linux kernel through 4.11.1 mishandles reference counts, which allows local users to cause a denial of service use-after-free or possibly have...
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 Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMITSTACK/RLIMINFINITY 1/4 of the size, but does not take the argument and environment pointers into account, which allows attackers to bypass this limitation. This affects Linux Kernel version...
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...

CVE-2017-1000365
CVE-2017-1000365 affects the Linux kernel where size limits for arguments and environment strings passed via RLIMIT_STACK/RLIMIT_INFINITY do not properly account for the argument/environment pointers, enabling a local attacker to potentially execute arbitrary code. The issue is described as a lim...

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...
