Description

This is a bug fix release in the stable 2.22 series.

- CVE-2018-4437

-- Processing maliciously crafted web content may lead to arbitrary code execution. Multiple memory corruption issues were addressed with improved memory handling.

  • Improved the logic to determine for which architectures to enable the JIT compiler support and USE_SYSTEM_MALLOC at build time.

  • Fix the build with ENABLE_VIDEO=OFF and ENABLE_OPENGL=OFF.

  • Fix several crashes.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
