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)

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

  - GNU Libc current is affected by: Re-mapping current     loaded library with malicious ELF file. The impact is:
    In worst case attacker may evaluate privileges. The     component is: libld. The attack vector is: Attacker     sends 2 ELF files to victim and asks to run ldd on it.
    ldd execute code. NOTE: Upstream comments indicate     'this is being treated as a non-security bug and no     real threat.'(CVE-2019-1010023)

  - Stack-based buffer overflow in the getaddrinfo function     in sysdeps/posix/getaddrinfo.c in the GNU C Library     (aka glibc or libc6) allows remote attackers to cause a     denial of service (crash) via vectors involving hostent     conversion. NOTE: this vulnerability exists because of     an incomplete fix for CVE-2013-4458.(CVE-2016-3706)

  - 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) 2.32 and earlier, when processing invalid input     sequences in the ISO-2022-JP-3 encoding, fails an     assertion in the code path and aborts the program,     potentially resulting in a denial of     service.(CVE-2021-3326)

  - 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)

  - The makecontext function in the GNU C Library (aka     glibc or libc6) before 2.25 creates execution contexts     incompatible with the unwinder on ARM EABI (32-bit)     platforms, which might allow context-dependent     attackers to cause a denial of service (hang), as     demonstrated by applications compiled using gccgo,     related to backtrace generation.(CVE-2016-6323)

  - 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)
