Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- The png_set_text_2 function in pngset.c in libpng 1.0.x before 1.0.59, 1.2.x before 1.2.49, 1.4.x before 1.4.11, and 1.5.x before 1.5.10 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted text chunk in a PNG image file, which triggers a memory allocation failure that is not properly handled, leading to a heap-based buffer overflow.(CVE-2011-3048)

- The png_handle_sCAL function in pngrutil.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 does not properly handle invalid sCAL chunks, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted PNG image that triggers the reading of uninitialized memory.(CVE-2011-2692)

- It was discovered that the png_get_PLTE() and png_set_PLTE() functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. In case an application tried to use these functions in combination with properly calculated palette sizes, this could lead to a buffer overflow or out-of-bounds reads. An attacker could exploit this to cause a crash or potentially execute arbitrary code by tricking an unsuspecting user into processing a specially crafted PNG image. However, the exact impact is dependent on the application using the library.(CVE-2015-8472)

- The png_err function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 makes a function call using a NULL pointer argument instead of an empty-string argument, which allows remote attackers to cause a denial of service (application crash) via a crafted PNG image.(CVE-2011-2691)

- Integer underflow in the png_check_keyword function in pngwutil.c in libpng 0.90 through 0.99, 1.0.x before 1.0.66, 1.1.x and 1.2.x before 1.2.56, 1.3.x and 1.4.x before 1.4.19, and 1.5.x before 1.5.26 allows remote attackers to have unspecified impact via a space character as a keyword in a PNG image, which triggers an out-of-bounds read.(CVE-2015-8540)

- Integer overflow in libpng, as used in Google Chrome before 17.0.963.56, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that trigger an integer truncation.(CVE-2011-3026)

- An array-indexing error was discovered in the png_convert_to_rfc1123() function of libpng. An attacker could possibly use this flaw to cause an out-of-bounds read by tricking an unsuspecting user into processing a specially crafted PNG image.(CVE-2015-7981)

- Buffer overflow in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4, when used by an application that calls the png_rgb_to_gray function but not the png_set_expand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image.(CVE-2011-2690)

- The png_format_buffer function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 allows remote attackers to cause a denial of service (application crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. NOTE: this vulnerability exists because of a CVE-2004-0421 regression. NOTE: this is called an off-by-one error by some sources.(CVE-2011-2501)

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.

Solution

Update the affected libpng packages.

How to Run

Here is how to run the EulerOS Virtualization 3.0.1.0 : libpng (EulerOS-SA-2019-1421) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Huawei Local Security Checks plugin family.
On the right side table select EulerOS Virtualization 3.0.1.0 : libpng (EulerOS-SA-2019-1421) plugin ID 124924.
Specify the target on the Settings tab and click to Save the scan.
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 EulerOS_SA-2019-1421.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a EulerOS_SA-2019-1421.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - EulerOS_SA-2019-1421.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 EulerOS_SA-2019-1421.nasl -t <IP/HOST>
