Cyber Security and Compilation issues.

Post by rudrakunal01 »

Hello Team,

I have 3 specific queries -
  • We have scanned binaries of Ver. 4.1.3 and found some vulnerabilities related to Cyber Security -
    CVE-2019-17542 | CVE-2019-17539 | CVE-2019-15942. Are these vulnerabilities resolved in later version FFmpeg 4.1.5 "al-Khwarizmi" ?
  • Where can I find source code of version 4.1.3 ?
  • We are getting following linking error while using version 4.1.5 in our application (using 64bit binaries), while version 4.1.3 and 4.2.2 are successfully compiled.
    Is there any specific headers / libraries we need to add in order to use ver 4.1.5.
