Question

Latest Flash Players do not work on RHEL 6 & 7, Centos 6 & 7, Scientific Linux 6 & 7, etc

It appears that the latest builds of the flash-plugin package DOES NOT WORK for:

 

  • Red Hat Enterprise Linux 6 & 7
  • CentOS 6 & 7
  • Scientific Linux 6 & 7
  • Oracle Linux 6 & 7

 

The reason for this appears to be because they have been compiled with a version of GLIBC that is not available on these systems. The packages install, but do not show or work in Firefox. When looking into the reason why, we get the following:

 

```

# ldd /usr/lib64/flash-plugin/libflashplayer.so
/usr/lib64/flash-plugin/libflashplayer.so: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /usr/lib64/flash-plugin/libflashplayer.so)
```

 

RHEL7 supports up to GLIBCXX_3.4.19

RHEL6 supports up to GLIBCXX_3.4.13

Newer versions than these are not available.

 

Affected versions of the flash plugin are:

32.0.0.293

32.0.0.303

It is  also logged as a bug at https://tracker.adobe.com/#/view/FP-4199058,but no-one from Adobe  appears to have taken a look at it.

For security reasons, Flash Player for Linux has been compiled with updated library dependencies. Please refer to the bottom of https://helpx.adobe.com/flash-player/release-note/readme-flash-player-linux.html for a list of library dependencies. To continue using Flash Player on Linux requires updating to a distro that supports these libraries.

"Upgrading to a more recent distribution" is not a viable solution, especially as RHEL7 support continues until 2024. We have roughly 800 RHEL7 Linux desktops. In order to upgrade these to RHEL8 would take in excess of a year and require substantial effort at which point Adobe Flash is end of life.

 

edit: I should add that I'm not asking for Flash to still work until 2024, but I do expect Flash to work until it's proposed retirement date in 2020. Rather than becoming "unsupported" with no advance warning.
