Subject: [PATCH] Fix a UAF resulting from a bug in BIO_new_NDEF
|
||||
|
||||
If the aux->asn1_cb() call fails in BIO_new_NDEF then the "out" BIO will
|
||||
be part of an invalid BIO chain. This causes a "use after free" when the
|
||||
BIO is eventually freed.
|
||||
|
||||
Based on an original patch by Viktor Dukhovni and an idea from Theo
|
||||
Buehler.
|
||||
|
||||
Thanks to Octavio Galland for reporting this issue.
