httpd fails to start with double free after updating to openssl-1.0.2k-23.el7_9

Solution Verified - Updated -


  • We updated openssl to openssl-1.0.2k-23.el7_9. After this, httpd is no longer able to start and error_logs show double free back traces like the following:

    *** Error in `/usr/sbin/httpd': double free or corruption (fasttop): 0x00005637ad2df900 ***
    ======= Backtrace: =========


  • Red Hat Enterprise Linux (RHEL) 7.x
  • openssl-1.0.2k-23.el7_9
  • httpd 2.4.6
  • OCSP stapling is enabled
