Arch Linux Security Advisory ASA-201801-3 ========================================= Severity: High Date : 2018-01-05 CVE-ID : CVE-2017-16995 CVE-2017-16996 CVE-2017-17449 CVE-2017-17558 CVE-2017-17712 CVE-2017-17805 CVE-2017-17806 CVE-2017-17852 CVE-2017-17853 CVE-2017-17854 CVE-2017-17855...

CVE-2017-17864

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 mishandles statesequal comparisons between the pointer data type and the UNKNOWNVALUE data type, which allows local users to obtain potentially sensitive address information, aka a "pointer leak."...

DEBIAN-CVE-2017-17856

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging the lack of stack-pointer alignment enforcement...

CVE-2017-17863

kernel/bpf/verifier.c in the Linux kernel 4.9.x through 4.9.71 does not check the relationship between pointer values and the BPF stack, which allows local users to cause a denial of service integer overflow or invalid memory access or possibly have unspecified other impact...

DEBIAN-CVE-2017-17864

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 mishandles statesequal comparisons between the pointer data type and the UNKNOWNVALUE data type, which allows local users to obtain potentially sensitive address information, aka a "pointer leak."...

DEBIAN-CVE-2017-17854

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service integer overflow and memory corruption or possibly have unspecified other impact by leveraging unrestricted integer values for pointer arithmetic...

DEBIAN-CVE-2017-17863

kernel/bpf/verifier.c in the Linux kernel 4.9.x through 4.9.71 does not check the relationship between pointer values and the BPF stack, which allows local users to cause a denial of service integer overflow or invalid memory access or possibly have unspecified other impact...

DEBIAN-CVE-2017-17853

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging incorrect BPFRSH signed bounds calculations...

DEBIAN-CVE-2017-17857

The checkstackboundary function in kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging mishandling of invalid variable stack read operations...

DEBIAN-CVE-2017-17862

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 ignores unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service...

DEBIAN-CVE-2017-17852

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging mishandling of 32-bit ALU ops...

DEBIAN-CVE-2017-17855

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging improper use of pointers in place of scalars...

DEBIAN-CVE-2017-16995

The checkaluop function in kernel/bpf/verifier.c in the Linux kernel through 4.4 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging incorrect sign extension...

Memory corruption

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact by leveraging incorrect BPFRSH signed bounds calculations...
