VLC 3.0.7

VLC released security updates that address several security issues than any other release of the VLC player. VLC 3.0.7 released with a fix for 43 security issues that include 2 high-security issues, 21 medium security issues, and 20 low-security issues.

The two high-security issues are an Out-of-Bound Write and a Stack Buffer Overflow. The Out-of-Bound Write resides in the faad2 library, a dependency of VLC and the Stack Buffer Overflow in the new RIST module.

The medium-security issues are mostly out-of-band reads, heap overflows, NULL-dereference, and use-after-free security issues. Those issues should not be exploitable with ASLR, but are important anyway, because they can crash VLC.

The low-security issues are mostly integer overflow, division by zero, and other out-of-band reads with no actual impact. Those issues are not exploitable, reads Jean-Baptiste Kempf blog post.

The highest number of vulnerabilities fixed as the European Commission included open source tools with EU-Free and Open Source Software Auditing (EU-FOSSA) project to improve the security of free software.
