cairo 1.16.0, in cairo_ft_apply_variations() in cairo-ft-font.c, would free memory using a free function incompatible with WebKit's fastMalloc, leading to an application crash with a "free(): invalid pointer" error.

An update of the cairo package has been released.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - cairo: infinite loop in the function _arc_error_normalized in the file cairo-arc.c (CVE-2019-6462)

  - cairo through 1.15.14 has an out-of-bounds stack-memory write during processing of a crafted document by     WebKitGTK+ because of the interaction between cairo-rectangular-scan-converter.c (the generate and     render_rows functions) and cairo-image-compositor.c (the _cairo_image_spans_and_zero function).
    (CVE-2018-18064)

  - cairo 1.16.0, in cairo_ft_apply_variations() in cairo-ft-font.c, would free memory using a free function     incompatible with WebKit's fastMalloc, leading to an application crash with a free(): invalid pointer     error. (CVE-2018-19876)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

According to the version of the cairo packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :
