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)

The remote NewStart CGSL host, running version MAIN 5.04, has glibc packages installed that are affected by multiple vulnerabilities:

  - elf/dl-load.c in ld.so in the GNU C Library (aka glibc     or libc6) through 2.11.2, and 2.12.x through 2.12.1,     does not properly handle a value of $ORIGIN for the     LD_AUDIT environment variable, which allows local users     to gain privileges via a crafted dynamic shared object     (DSO) located in an arbitrary directory. (CVE-2010-3847)

  - ld.so in the GNU C Library (aka glibc or libc6) before     2.11.3, and 2.12.x before 2.12.2, does not properly     restrict use of the LD_AUDIT environment variable to     reference dynamic shared objects (DSOs) as audit     objects, which allows local users to gain privileges by     leveraging an unsafe DSO located in a trusted library     directory, as demonstrated by libpcprofile.so.
    (CVE-2010-3856)

  - 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)

  - Stack-based buffer 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 that triggers a malloc failure and use of     the alloca function. (CVE-2012-4424)

  - A flaw was found in the regular expression matching     routines that process multibyte character input. If an     application utilized the glibc regular expression     matching mechanism, an attacker could provide specially-     crafted input that, when processed, would cause the     application to crash. (CVE-2013-0242)

  - 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, CVE-2013-4458)

  - pt_chown in GNU C Library (aka glibc or libc6) before     2.18 does not properly check permissions for tty files,     which allows local users to change the permission on the     files and obtain access to arbitrary pseudo-terminals by     leveraging a FUSE file system. (CVE-2013-2207)

  - 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)

  - Multiple integer overflow flaws, leading to heap-based     buffer overflows, were found in glibc's memory allocator     functions (pvalloc, valloc, and memalign). If an     application used such a function, it could cause the     application to crash or, potentially, execute arbitrary     code with the privileges of the user running the     application. (CVE-2013-4332)

  - 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)

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