The remote NewStart CGSL host, running version MAIN 6.02, has glibc packages installed that are affected by multiple vulnerabilities:

  - The idna_to_ascii_4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to     cause a denial of service (out-of-bounds read and crash) via 64 bytes of input. (CVE-2016-6261)

  - The stringprep_utf8_nfkc_normalize function in lib/nfkc.c in libidn before 1.33 allows context-dependent     attackers to cause a denial of service (out-of-bounds read and crash) via crafted UTF-8 data.
    (CVE-2016-6263)

  - A memory leak in glibc 2.1.1 (released on May 24, 1999) can be reached and amplified through the     LD_HWCAP_MASK environment variable. Please note that many versions of glibc are not vulnerable to this     issue if patched for CVE-2017-1000366. (CVE-2017-1000408)

  - A buffer overflow in glibc 2.5 (released on September 29, 2006) and can be triggered through the     LD_LIBRARY_PATH environment variable. Please note that many versions of glibc are not vulnerable to this     issue if patched for CVE-2017-1000366. (CVE-2017-1000409)

  - Integer overflow in the decode_digit function in puny_decode.c in Libidn2 before 2.0.4 allows remote     attackers to cause a denial of service or possibly have unspecified other impact. (CVE-2017-14062)

  - The GNU C Library (aka glibc or libc6) before 2.27 contains an off-by-one error leading to a heap-based     buffer overflow in the glob function in glob.c, related to the processing of home directories using the ~     operator followed by a long string. (CVE-2017-15670)

  - The glob function in glob.c in the GNU C Library (aka glibc or libc6) before 2.27 contains a buffer     overflow during unescaping of user names with the ~ operator. (CVE-2017-15804)

  - elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26 mishandles RPATH and RUNPATH     containing $ORIGIN for a privileged (setuid or AT_SECURE) program, which allows local users to gain     privileges via a Trojan horse library in the current working directory, related to the fillin_rpath and     decompose_rpath functions. This is associated with misinterpretion of an empty RPATH/RUNPATH token as the     ./ directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very     uncommon; most likely, no such program is shipped with any common Linux distribution. (CVE-2017-16997)

  - The malloc function in the GNU C Library (aka glibc or libc6) 2.26 could return a memory block that is too     small if an attempt is made to allocate an object whose size is close to SIZE_MAX, potentially leading to     a subsequent heap overflow. This occurs because the per-thread cache (aka tcache) feature enables a code     path that lacks an integer overflow check. (CVE-2017-17426)

  - An SSE2-optimized memmove implementation for i386 in sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S     in the GNU C Library (aka glibc or libc6) 2.21 through 2.27 does not correctly perform the overlapping     memory check if the source memory range spans the middle of the address space, resulting in corrupt data     being produced by the copy operation. This may disclose information to context-dependent attackers, or     result in a denial of service, or, possibly, code execution. (CVE-2017-18269)

  - In glibc 2.26 and earlier there is confusion in the usage of getcwd() by realpath() which can be used to     write before the destination buffer leading to a buffer underflow and potential code execution.
    (CVE-2018-1000001)

  - stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very     long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit     architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution.
    (CVE-2018-11236)

  - An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27     and earlier may write data beyond the target buffer, leading to a buffer overflow in
    __mempcpy_avx512_no_vzeroupper. (CVE-2018-11237)

  - In the GNU C Library (aka glibc or libc6) through 2.28, attempting to resolve a crafted hostname via     getaddrinfo() leads to the allocation of a socket descriptor that is not closed. This is related to the     if_nametoindex() function. (CVE-2018-19591)

  - 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 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)

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

  - It was discovered that the nss_files backend for the     Name Service Switch in glibc would return incorrect     data to applications or corrupt the heap (depending on     adjacent heap contents). A local attacker could     potentially use this flaw to execute arbitrary code on     the system.(CVE-2015-5277)

  - A directory traveral flaw was found in the way glibc     loaded locale files. An attacker able to make an     application use a specially crafted locale name value     (for example, specified in an LC_* environment     variable) could possibly use this flaw to execute     arbitrary code with the privileges of that     application.(CVE-2014-0475)

  - It was found that out-of-range time values passed to     the strftime() function could result in an     out-of-bounds memory access. This could lead to     application crash or, potentially, information     disclosure.(CVE-2015-8776)

  - The GNU C Library (aka glibc or libc6) before 2.27     contains an off-by-one error leading to a heap-based     buffer overflow in the glob function in glob.c, related     to the processing of home directories using the ~     operator followed by a long string.(CVE-2017-15670)

  - The PTR_MANGLE implementation in the GNU C Library (aka     glibc or libc6) 2.4, 2.17, and earlier, and Embedded     GLIBC (EGLIBC) does not initialize the random value for     the pointer guard, which makes it easier for     context-dependent attackers to control execution flow     by leveraging a buffer-overflow vulnerability in an     application and using the known zero value pointer     guard to calculate a pointer address.(CVE-2013-4788)

  - An out-of-bounds read flaw was found in the way glibc's     iconv() function converted certain encoded data to     UTF-8. An attacker able to make an application call the     iconv() function with a specially crafted argument     could use this flaw to crash that     application.(CVE-2014-6040)

  - A stack overflow vulnerability was found in
    _nss_dns_getnetbyname_r. On systems with nsswitch     configured to include ''networks: dns'' with a     privileged or network-facing service that would attempt     to resolve user-provided network names, an attacker     could provide an excessively long network name,     resulting in stack corruption and code     execution.(CVE-2016-3075)

  - Integer overflow in string/strcoll_l.c in the GNU C     Library (aka glibc or libc6) 2.17 and earlier allows     context-dependent attackers to cause a denial of     service (crash) or possibly execute arbitrary code via     a long string, which triggers a heap-based buffer     overflow.(CVE-2012-4412)

  - A heap-based buffer overflow flaw was found in glibc's     swscanf() function. An attacker able to make an     application call the swscanf() function could use this     flaw to crash that application or, potentially, execute     arbitrary code with the permissions of the user running     the application.(CVE-2015-1472)

  - It was found that getaddrinfo() did not limit the     amount of stack memory used during name resolution. An     attacker able to make an application resolve an     attacker-controlled hostname or IP address could     possibly cause the application to exhaust all stack     memory and crash.(CVE-2013-1914)

  - A stack overflow vulnerability was found in nan*     functions that could cause applications, which process     long strings with the nan function, to crash or,     potentially, execute arbitrary code.(CVE-2014-9761)

  - An out-of-bounds write flaw was found in the way the     glibc's readdir_r() function handled file system     entries longer than the NAME_MAX character constant. A     remote attacker could provide a specially crafted NTFS     or CIFS file system that, when processed by an     application using readdir_r(), would cause that     application to crash or, potentially, allow the     attacker to execute arbitrary code with the privileges     of the user running the application.(CVE-2013-4237)

  - It was discovered that, under certain circumstances,     glibc's getaddrinfo() function would send DNS queries     to random file descriptors. An attacker could     potentially use this flaw to send DNS queries to     unintended recipients, resulting in information     disclosure or data loss due to the application     encountering corrupted data.(CVE-2013-7423)

  - A buffer overflow flaw was found in the way glibc's     gethostbyname_r() and other related functions computed     the size of a buffer when passed a misaligned buffer as     input. An attacker able to make an application call any     of these functions with a misaligned buffer could use     this flaw to crash the application or, potentially,     execute arbitrary code with the permissions of the user     running the application.(CVE-2015-1781)

  - The nss_dns implementation of getnetbyname in GNU C     Library (aka glibc) before 2.21, when the DNS backend     in the Name Service Switch configuration is enabled,     allows remote attackers to cause a denial of service     (infinite loop) by sending a positive answer while a     network name is being process.(CVE-2014-9402)

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
