Subject: [PATCH 10/11] gtlspassword: Forbid very long TLS passwords
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8
|
||
Content-Transfer-Encoding: 8bit
|
||
|
||
The public API `g_tls_password_set_value_full()` (and the vfunc it
|
||
invokes) can only accept a `gssize` length. Ensure that nul-terminated
|
||
strings passed to `g_tls_password_set_value()` can’t exceed that length.
|
||
Use `g_memdup2()` to avoid an overflow if they’re longer than
|
||
`G_MAXUINT` similarly.
|
||
|

Helps: #2319
