neosys007 opened a new pull request, #3355:
URL: https://github.com/apache/thrift/pull/3355
…t_ssl_error()
thrift_ssl_socket_get_ssl_error() still builds SSL error messages in a fixed
stack buffer while tracking remaining space with a signed counter that is
updated by subtracting snprintf() return values.
If the formatted error text is long enough, that counter can underflow and
the later writes can walk past the intended buffer boundaries.
Build the error message with GString instead so the helper no longer depends
on hand-rolled remaining-space arithmetic.
<!-- Explain the changes in the pull request below: -->
<!-- We recommend you review the checklist/tips before submitting a pull
request. -->
- [ ] Did you create an [Apache
Jira](https://issues.apache.org/jira/projects/THRIFT/issues/) ticket?
([Request account here](https://selfserve.apache.org/jira-account.html), not
required for trivial changes)
- [ ] If a ticket exists: Does your pull request title follow the pattern
"THRIFT-NNNN: describe my issue"?
- [ ] Did you squash your changes to a single commit? (not required, but
preferred)
- [ ] Did you do your best to avoid breaking changes? If one was needed,
did you label the Jira ticket with "Breaking-Change"?
- [ ] If your change does not involve any code, include `[skip ci]` anywhere
in the commit message to free up build resources.
