    This update fixes a wide range of vulnerabilities. A significant portion     affects character set conversion.

    CVE-2016-10228

        The iconv program in the GNU C Library 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-2019-19126

        On the x86-64 architecture, the GNU C Library 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-2019-25013

        The iconv feature in the GNU C Library, when processing invalid         multi-byte input sequences in the EUC-KR encoding, may have a buffer         over-read.

    CVE-2020-10029

        The GNU C Library 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-2020-1752

        A use-after-free vulnerability introduced in glibc 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.

    CVE-2020-27618

        The iconv function in the GNU C Library, 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-2020-6096

        An exploitable signed comparison vulnerability exists in the ARMv7         memcpy() implementation of GNU glibc. 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-2021-27645

        The nameserver caching daemon (nscd) in the GNU C Library, 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. This is related to netgroupcache.c.

    CVE-2021-3326

        The iconv function in the GNU C Library, 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-2021-33574

        The mq_notify function in the GNU C Library 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-2021-35942

        The wordexp function in the GNU C Library 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-2021-3999

        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-2022-23218

        The deprecated compatibility function svcunix_create in the sunrpc         module of the GNU C Library copies its path argument on the stack         without validating its length, which may result in a buffer overflow,         potentially resulting in a denial of service or (if an application         is not built with a stack protector enabled) arbitrary code execution.

    CVE-2022-23219

        The deprecated compatibility function clnt_create in the sunrpc module         of the GNU C Library copies its hostname argument on the stack without         validating its length, which may result in a buffer overflow,         potentially resulting in a denial of service or (if an application is         not built with a stack protector enabled) arbitrary code execution.


    For Debian 10 buster, these problems have been fixed in version     2.28-10+deb10u2.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2022:0122 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-19126:
    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-2020-10029:
    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-2020-1751:
    An out-of-bounds write vulnerability was found in glibc before 2.31 when handling signal trampolines on     PowerPC. Specifically, the backtrace function did not properly check the array bounds when storing the     frame address, resulting in a denial of service or potential code execution. The highest threat from this     vulnerability is to system availability.

    CVE-2020-1752:
    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-2020-6096:
    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.

An update of the glibc package has been released.

This update for glibc fixes the following issues :

  - CVE-2020-1752: Fixed a use after free in glob which     could have allowed a local attacker to create a     specially crafted path that, when processed by the glob     function, could potentially have led to arbitrary code     execution (bsc#1167631). This update was imported from     the SUSE:SLE-15:Update update project.

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

  - The glibc package contains standard libraries which are     used by multiple programs on the system. In order to     save disk space and memory, as well as to make     upgrading easier, common system code is kept in one     place and shared between programs. This particular     package contains the most important sets of shared     libraries: the standard C library and the standard math     library. Without these two libraries, a Linux system     will not function.Security Fix(es):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)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)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)GNU Libc current is affected by:

The version of glibc installed on the remote host is prior to 2.26-37. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1944 advisory.

    A vulnerability was discovered in glibc where the LD_PREFER_MAP_32BIT_EXEC environment variable is not     ignored when running binaries with the setuid flag on x86_64 architectures. This allows an attacker to     force system to utilize only half of the memory (making the system think the software is 32-bit only),     thus lowering the amount of memory being used with address space layout randomization (ASLR). The highest     threat is confidentiality although the complexity of attack is high. The affected application must already     have other vulnerabilities for this flaw to be usable. (CVE-2019-19126)

    A flaw was found in glibc in versions prior to 2.32. Pseudo-zero values are not validated causing a stack     corruption due to a stack-based overflow. The highest threat from this vulnerability is to system     availability. (CVE-2020-10029)

    A use-after-free vulnerability was found in glibc 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.
