1 CVE-2017-1000379 264 2017-06-19 2017-08-11
7.2
Admin Local Low Not required Complete Complete Complete
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.
2 CVE-2017-1000371 264 2017-06-19 2017-11-05
7.2
None Local Low Not required Complete Complete Complete
The offset2lib patch as used by the Linux Kernel contains a vulnerability, if RLIMIT_STACK is set to RLIM_INFINITY 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 minimum distance between the end of the PIE binary's read-write segment and the start of the stack becomes small enough that the stack guard page can be jumped over by an attacker. This affects Linux Kernel version 4.11.5. This is a different issue than CVE-2017-1000370 and CVE-2017-1000365. This issue appears to be limited to i386 based systems.
3 CVE-2017-1000370 264 2017-06-19 2017-11-05
7.2
Admin Local Low Not required Complete Complete Complete
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 offset2lib patch. This affects Linux Kernel version 4.11.5 and earlier. This is a different issue than CVE-2017-1000371. This issue appears to be limited to i386 based systems.
4 CVE-2017-1000365 264 Bypass 2017-06-19 2017-11-03
7.2
Admin Local Low Not required Complete Complete Complete
The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (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 versions 4.11.5 and earlier. It appears that this feature was introduced in the Linux Kernel version 2.6.23.
5 CVE-2017-1000364 119 Overflow Bypass 2017-06-19 2017-11-03
6.2
None Local High Not required Complete Complete Complete
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).
6 CVE-2017-1000251 119 Exec Code Overflow 2017-09-12 2017-12-08
8.3
Admin Local Network Low Not required Complete Complete Complete
The native Bluetooth stack in the Linux Kernel (BlueZ), starting at the Linux kernel version 2.6.32 and up to and including 4.13.1, are vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space.
7 CVE-2017-16994 200 +Info 2017-11-27 2017-12-07
2.1
None Local Low Not required Partial None None
The walk_hugetlb_range function in mm/pagewalk.c in the Linux kernel before 4.14.2 mishandles holes in hugetlb ranges, which allows local users to obtain sensitive information from uninitialized kernel memory via crafted use of the mincore() system call.
8 CVE-2017-16939 264 DoS +Priv 2017-11-24 2017-12-08
7.2
None Local Low Not required Complete Complete Complete
The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages.
9 CVE-2017-15115 416 DoS 2017-11-15 2017-12-03
7.2
None Local Low Not required Complete Complete Complete
The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel before 4.14 does not check whether the intended netns is used in a peel-off action, which allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls.
