lftp_ssl: deinitialize the lftp_ssl_openssl_instance #723

Open tabraham opened 10 months ago

tabraham commented 10 months ago

If the instance isn't deinitialized prior to exit, the OPENSSL_cleanup exit handler may run before the lftp_ssl_openssl_instance destructor on exit resulting in a segfault.

This fixes a null deref on exit.

Fixes #716
