Subject: [PATCH 11/11] giochannel: Forbid very long line terminator strings
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8
|
||
Content-Transfer-Encoding: 8bit
|
||
|
||
The public API `GIOChannel.line_term_len` is only a `guint`. Ensure that
|
||
nul-terminated strings passed to `g_io_channel_set_line_term()` can’t
|
||
exceed that length. Use `g_memdup2()` to avoid a warning (`g_memdup()`
|
||
is due to be deprecated), but not to avoid a bug, since it’s also
|
||
limited to `G_MAXUINT`.
|
||
