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.

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)

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:
    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.(CVE-2019-1010023)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 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)
