An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27 and earlier may write data beyond the target buffer, leading to a buffer overflow in __mempcpy_avx512_no_vzeroupper.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2018-3092 advisory.

  - elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26 mishandles RPATH and RUNPATH     containing $ORIGIN for a privileged (setuid or AT_SECURE) program, which allows local users to gain     privileges via a Trojan horse library in the current working directory, related to the fillin_rpath and     decompose_rpath functions. This is associated with misinterpretion of an empty RPATH/RUNPATH token as the     ./ directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very     uncommon; most likely, no such program is shipped with any common Linux distribution. (CVE-2017-16997)

  - An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library     (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that     is too small, potentially leading to heap corruption. (CVE-2018-6485)

  - stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very     long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit     architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution.
    (CVE-2018-11236)

  - An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27     and earlier may write data beyond the target buffer, leading to a buffer overflow in
    __mempcpy_avx512_no_vzeroupper. (CVE-2018-11237)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version MAIN 6.02, has glibc packages installed that are affected by multiple vulnerabilities:

  - The idna_to_ascii_4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to     cause a denial of service (out-of-bounds read and crash) via 64 bytes of input. (CVE-2016-6261)

  - The stringprep_utf8_nfkc_normalize function in lib/nfkc.c in libidn before 1.33 allows context-dependent     attackers to cause a denial of service (out-of-bounds read and crash) via crafted UTF-8 data.
    (CVE-2016-6263)

  - A memory leak in glibc 2.1.1 (released on May 24, 1999) can be reached and amplified through the     LD_HWCAP_MASK environment variable. Please note that many versions of glibc are not vulnerable to this     issue if patched for CVE-2017-1000366. (CVE-2017-1000408)

  - A buffer overflow in glibc 2.5 (released on September 29, 2006) and can be triggered through the     LD_LIBRARY_PATH environment variable. Please note that many versions of glibc are not vulnerable to this     issue if patched for CVE-2017-1000366. (CVE-2017-1000409)

  - Integer overflow in the decode_digit function in puny_decode.c in Libidn2 before 2.0.4 allows remote     attackers to cause a denial of service or possibly have unspecified other impact. (CVE-2017-14062)

  - The GNU C Library (aka glibc or libc6) before 2.27 contains an off-by-one error leading to a heap-based     buffer overflow in the glob function in glob.c, related to the processing of home directories using the ~     operator followed by a long string. (CVE-2017-15670)

  - The glob function in glob.c in the GNU C Library (aka glibc or libc6) before 2.27 contains a buffer     overflow during unescaping of user names with the ~ operator. (CVE-2017-15804)

  - elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26 mishandles RPATH and RUNPATH     containing $ORIGIN for a privileged (setuid or AT_SECURE) program, which allows local users to gain     privileges via a Trojan horse library in the current working directory, related to the fillin_rpath and     decompose_rpath functions. This is associated with misinterpretion of an empty RPATH/RUNPATH token as the     ./ directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very     uncommon; most likely, no such program is shipped with any common Linux distribution. (CVE-2017-16997)

  - The malloc function in the GNU C Library (aka glibc or libc6) 2.26 could return a memory block that is too     small if an attempt is made to allocate an object whose size is close to SIZE_MAX, potentially leading to     a subsequent heap overflow. This occurs because the per-thread cache (aka tcache) feature enables a code     path that lacks an integer overflow check. (CVE-2017-17426)

  - An SSE2-optimized memmove implementation for i386 in sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S     in the GNU C Library (aka glibc or libc6) 2.21 through 2.27 does not correctly perform the overlapping     memory check if the source memory range spans the middle of the address space, resulting in corrupt data     being produced by the copy operation. This may disclose information to context-dependent attackers, or     result in a denial of service, or, possibly, code execution. (CVE-2017-18269)

  - In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to     write before the destination buffer leading to a buffer underflow and potential code execution.
    (CVE-2018-1000001)

  - stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very     long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit     architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution.
    (CVE-2018-11236)

  - An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27     and earlier may write data beyond the target buffer, leading to a buffer overflow in
    __mempcpy_avx512_no_vzeroupper. (CVE-2018-11237)

  - In the GNU C Library (aka glibc or libc6) through 2.28, attempting to resolve a crafted hostname via     getaddrinfo() leads to the allocation of a socket descriptor that is not closed. This is related to the     if_nametoindex() function. (CVE-2018-19591)

  - In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-     based buffer over-read via an attempted case-insensitive regular-expression match. (CVE-2019-9169)

  - The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range     reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when     passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to     sysdeps/ieee754/ldbl-96/e_rem_pio2l.c. (CVE-2020-10029)

__mempcpy_avx512_no_vzeroupper (bsc#1094154)

Non security bugs fixed: Fix crash in resolver on memory allocation failure (bsc#1086690)

This update removes a misleading comment from the documentation of the `abort` function (RHBZ#1615608). A minor security vulnerability, CVE-2018-11237, a buffer overflow in mempcpy for Xeon Phi (RHBZ#1581275) has been addressed.

The update also fixes the waiters-after-spinning case in the `pthread_cond_broadcast` function (RHBZ#1622669). Two bugs in the CPUID processing on x86 are also fixed (upstream bugs 23456 and 23459). The verification of vtables for stdio is improved (upstream bugs 23236 and 23313). A test case under a non-free license is removed (upstream bug 23363). The `if_nametoindex` now checks the length of interface names (upstream bug 22442). `getifaddrs` no longer returns interfaces with NULL names (upstream bug 23171). C++ compatibility of `iseqsig` has been improved (upstream bug 23171). A kernel header interaction issue related to `struct timespec` was addressed (upstream bug 23349).
