Synopsis
The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.
Description
According to the versions of the libpng12 package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :
- 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.i1/4^CVE-2015-7981i1/4%0
- 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.i1/4^CVE-2015-8126i1/4%0
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 libpng12 packages.
