Stack-based buffer overflow in the glob implementation in GNU C Library (aka glibc) before 2.24, when GLOB_ALTDIRFUNC is used, allows context-dependent attackers to cause a denial of service (crash) via a long name.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary     libraries (CVE-2017-16997)

  - glibc: regular-expression match via proceed_next_node in posix/regexec.c leads to heap-based buffer over-     read (CVE-2019-9169)

  - The posix_spawn_file_actions_addopen function in glibc before 2.20 does not copy its path argument in     accordance with the POSIX specification, which allows context-dependent attackers to trigger use-after-     free vulnerabilities. (CVE-2014-4043)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary     libraries (CVE-2017-16997)

  - glibc: regular-expression match via proceed_next_node in posix/regexec.c leads to heap-based buffer over-     read (CVE-2019-9169)

  - In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/regcomp.c misparses     alternatives, which allows attackers to cause a denial of service (assertion failure and application exit)     or trigger an incorrect result by attempting a regular-expression match. (CVE-2009-5155)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to the versions of the glibc packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - In the GNU C Library (aka glibc or libc6) through 2.28,     the getaddrinfo function would successfully parse a     string that contained an IPv4 address followed by     whitespace and arbitrary characters, which could lead     applications to incorrectly assume that it had parsed a     valid string, without the possibility of embedded HTTP     headers or other potentially dangerous     substrings.(CVE-2016-10739)

  - Stack-based buffer overflow in the glob implementation     in GNU C Library (aka glibc) before 2.24, when     GLOB_ALTDIRFUNC is used, allows context-dependent     attackers to cause a denial of service (crash) via a     long name.(CVE-2016-1234)

  - Use-after-free vulnerability in the clntudp_call     function in sunrpc/clnt_udp.c in the GNU C Library (aka     glibc or libc6) before 2.26 allows remote attackers to     have unspecified impact via vectors related to error     path.(CVE-2017-12133)

  - In the GNU C Library (aka glibc or libc6) through 2.29,     check_dst_limits_calc_pos_1 in posix/regexec.c has     Uncontrolled Recursion, as demonstrated by     '(\227|)(\\1\\1|t1|\\\2537)+' in grep.(CVE-2018-20796)

  - ** DISPUTED ** In the GNU C Library (aka glibc or     libc6) through 2.29, check_dst_limits_calc_pos_1 in     posix/regexec.c has Uncontrolled Recursion, as     demonstrated by '(|)(\\1\\1)*' in grep, a different     issue than CVE-2018-20796. NOTE: the software     maintainer disputes that this is a vulnerability     because the behavior occurs only with a crafted     pattern.(CVE-2019-9192)

Several vulnerabilities have been fixed in the Debian GNU C Library, eglibc :

CVE-2016-1234

Alexander Cherepanov discovered that the glibc's glob implementation suffered from a stack-based buffer overflow when it was called with the GLOB_ALTDIRFUNC flag and encountered a long file name.

CVE-2016-3075

The getnetbyname implementation in nss_dns was susceptible to a stack overflow and a crash if it was invoked on a very long name.

CVE-2016-3706

Michael Petlan reported that getaddrinfo copied large amounts of address data to the stack, possibly leading to a stack overflow. This complements the fix for CVE-2013-4458.

For Debian 7 'Wheezy', these problems have been fixed in version 2.13-38+deb7u11.

We recommend you to upgrade your eglibc packages.
