Details
Description:
During initialization of the crypto subsystem libtransmission tries to initialize an rc4 context. This seems to always fail on openssl 3.0 leading to a followup segfault. Additional info: * transmission-gtk/libtransmission: 3.00-5 * openssl: 3.0.7-2 * https://github.com/transmission/transmission/issues/1777 also mentions abort during rc4 init, the fix to use another RC4 implementation seems not to be in the release version of transmission. Steps to reproduce: * Try to download a torrent in transmission-gtk that uses encrypted connections.
