原文摘录

摘自原文(1461 字符中的一小部分)
**Summary:** During the course of testing putty-0.70-2019-02-12.75dda5e on Fedora 29 compiled with clang version 7.0.1 (Fedora 7.0.1-1.fc29), we discovered it was possible to abort a remote client by streaming data at it in such a way as to trigger an assertion failure.
原文中的代码
putty: unix/gtkwin.c:3801: void do_text_internal(GtkFrontend *, int, int, wchar_t *, int, unsigned long, int, truecolour): Assertion `len == 1' failed.
