[Security] Bump excon from 0.62.0 to 0.82.0

[dependabot-preview]

Bumps excon from 0.62.0 to 0.82.0. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Race condition when using persistent connections There was a race condition around persistent connections, where a connection which is interrupted (such as by a timeout) would leave data on the socket. Subsequent requests would then read this data, returning content from the previous response. The race condition window appears to be short, and it would be difficult to purposefully exploit this.

Users can workaround the problem by disabling persistent connections, though this may cause performance implications.

Patched versions: >= 0.71.0 Unaffected versions: none
