(CVE-2016-10228)

  - On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the     LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition,     allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass     ASLR for a setuid program. (CVE-2019-19126)

  - The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-     byte input sequences in the EUC-KR encoding, may have a buffer over-read. (CVE-2019-25013)

  - 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)

  - A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde     expansion was carried out. Directory paths containing an initial tilde followed by a valid username were     affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path     that, when processed by the glob function, would potentially lead to arbitrary code execution. This was     fixed in version 2.32. (CVE-2020-1752)

  - The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid     multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance     the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a     different vulnerability from CVE-2016-10228. (CVE-2020-27618)

  - An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc     2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative     value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the     'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-     of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows     for program execution to continue in scenarios where a segmentation fault or crash should have occurred.
    The dangers occur in that subsequent execution and iterations of this code will be executed with this     corrupted data. (CVE-2020-6096)

  - The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when     processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in     degraded service or Denial of Service on the local system.

  - The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It     may use the notification thread attributes object (passed through its struct sigevent parameter) after it     has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified     other impact. (CVE-2021-33574)

  - The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in     parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in     a denial of service or disclosure of information. This occurs because atoi was used but strtoul should     have been used to ensure correct calculations. (CVE-2021-35942)

  - A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory     corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and     size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and     escalate their privileges on the system. (CVE-2021-3999)

  - The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text     containing an irreversible character, fails an assertion in the code path and aborts the program,     potentially resulting in a denial of service. (CVE-2020-29562)

  - sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-     based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with     a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to     sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because     of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words,     the reference to 2.23 is intentional despite the mention of Fixed for glibc 2.33 in the 26649 reference.

The version of glibc installed on the remote host is prior to 2.26-41. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1605 advisory.

  - The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple     suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite     loop when processing invalid multi-byte input sequences, leading to a denial of service. (CVE-2016-10228)

  - The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-     byte input sequences in the EUC-KR encoding, may have a buffer over-read. (CVE-2019-25013)

  - The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text     containing an irreversible character, fails an assertion in the code path and aborts the program,     potentially resulting in a denial of service. (CVE-2020-29562)

  - An exploitable signed comparison vulnerability exists in the ARMv7 memcpy() implementation of GNU glibc     2.30.9000. Calling memcpy() (on ARMv7 targets that utilize the GNU glibc implementation) with a negative     value for the 'num' parameter results in a signed comparison vulnerability. If an attacker underflows the     'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-     of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows     for program execution to continue in scenarios where a segmentation fault or crash should have occurred.
    The dangers occur in that subsequent execution and iterations of this code will be executed with this     corrupted data. (CVE-2020-6096)

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

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

  - Stack-based buffer overflow in the clntudp_call     function in sunrpc/clnt_udp.c in the GNU C Library (aka     glibc or libc6) allows remote servers to cause a denial     of service (crash) or possibly unspecified other impact     via a flood of crafted ICMP and UDP     packets.(CVE-2016-4429)

  - Integer overflow in the strxfrm function in the GNU C     Library (aka glibc or libc6) before 2.21 allows     context-dependent attackers to cause a denial of     service (crash) or possibly execute arbitrary code via     a long string, which triggers a stack-based buffer     overflow.(CVE-2015-8982)

  - 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)

  - res_query in libresolv in glibc before 2.25 allows     remote attackers to cause a denial of service (NULL     pointer dereference and process crash).(CVE-2015-5180)

  - A buffer overflow has been discovered in the GNU C     Library (aka glibc or libc6) in the
    __mempcpy_avx512_no_vzeroupper function when particular     conditions are met. An attacker could use this     vulnerability to cause a denial of service or     potentially execute code.(CVE-2018-11237)

  - 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 iconv program in the GNU C Library (aka glibc or     libc6) 2.25 and earlier, when invoked with the -c     option, enters an infinite loop when processing invalid     multi-byte input sequences, leading to a denial of     service.(CVE-2016-10228)

  - The DNS stub resolver in the GNU C Library (aka glibc     or libc6) before version 2.26, when EDNS support is     enabled, will solicit large UDP responses from name     servers, potentially simplifying off-path DNS spoofing     attacks due to IP fragmentation.(CVE-2017-12132)
