According to the versions of the cairo packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :
An issue was discovered in cairo 1.16.0. There is an infinite loop in the function _arc_error_normalized in the file cairo-arc.c, related to
_arc_max_angle_for_tolerance_normalized.(CVE-2019-6462)
An issue was discovered in cairo 1.16.0. There is an assertion problem in the function
_cairo_arc_in_direction in the file cairo-arc.c.(CVE-2019-6461)
Cairo version 1.15.4 is vulnerable to a NULL pointer dereference related to the FT_Load_Glyph and FT_Render_Glyph resulting in an application crash.(CVE-2017-7475)
A flaw was found in cairo’s image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo’s image-compositor (for example, by convincing a user to open a file in an application using cairo, or if an application uses cairo on untrusted input) to cause a stack buffer overflow -> out-of-bounds WRITE. The highest impact from this vulnerability is to confidentiality, integrity, as well as system availability.(CVE-2020-35492)
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.
