Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade the vulnerable CGSL glibc packages. Note that updated packages may not be available yet. Please contact ZTE for more information.

How to Run

Here is how to run the NewStart CGSL MAIN 5.04 : glibc Multiple Vulnerabilities (NS-SA-2019-0012) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

  1. Click to start a New Scan.
  2. Select Advanced Scan.
  3. Navigate to the Plugins tab.
  4. On the top right corner click to Disable All plugins.
  5. On the left side table select NewStart CGSL Local Security Checks plugin family.
  6. On the right side table select NewStart CGSL MAIN 5.04 : glibc Multiple Vulnerabilities (NS-SA-2019-0012) plugin ID 127161.
  7. Specify the target on the Settings tab and click to Save the scan.
  8. Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl newstart_cgsl_NS-SA-2019-0012_glibc.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a newstart_cgsl_NS-SA-2019-0012_glibc.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - newstart_cgsl_NS-SA-2019-0012_glibc.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state newstart_cgsl_NS-SA-2019-0012_glibc.nasl -t <IP/HOST>

Go back to menu.
