----------------------------------
Summary: pn_ssl_get_{protocol|cypher}_name() may segfault when
called by bindings
Key: PROTON-1453
URL: https://issues.apache.org/jira/browse/PROTON-1453
Project: Qpid Proton
Issue Type: Bug
Components: proton-c
Affects Versions: 0.17.0
Reporter: Ken Giusti
Assignee: Ken Giusti
Fix For: 0.18.0
the pn_ssl_get_password/cipher_name method takes a target buffer and length and
if the name is known it is copied to the buffer (null terminated) and true is
returned.
However if the name is not known (not yet present) the method returns false and
leaves the buffer untouched.
This is fine for correctly behaving C programs, but the swig generated code
always assumes the output buffer contains a properly terminated string whether
or not the return value is true. The swigged code unconditionally calls
strlen() on the returned buffer.
