Subject: [PATCH] Fix vulnerabilities in GSS message token handling
In gss_krb5int_unseal_token_v3() and gss_krb5int_unseal_v3_iov(),
verify the Extra Count field of CFX wrap tokens against the encrypted
header. Reported by Jacob Champion.
In gss_krb5int_unseal_token_v3(), check for a decrypted plaintext
length too short to contain the encrypted header and extra count
bytes. Reported by Jacob Champion.
In kg_unseal_iov_token(), separately track the header IOV length and
complete token length when parsing the token's ASN.1 wrapper. This
fix contains modified versions of functions from k5-der.h and
util_token.c; this duplication will be cleaned up in a future commit.
CVE-2024-37370:
In MIT krb5 release 1.3 and later, an attacker can modify the
plaintext Extra Count field of a confidential GSS krb5 wrap token,
causing the unwrapped token to appear truncated to the application.
CVE-2024-37371:
In MIT krb5 release 1.3 and later, an attacker can cause invalid
memory reads by sending message tokens with invalid length fields.

From 5f0023d5f05e95021a7caa1193f76f86871222ce Mon Sep 17 00:00:00 2001
From: Andreas Schneider <asn@samba.org>
Date: Wed, 8 May 2024 10:10:56 +0200
Subject: [PATCH] Handle empty initial buffer in IAKERB initiator
Section 5.19 of RFC 2744 (about gss_init_sec_context) states,
"Initially, the input_token parameter should be specified either as
GSS_C_NO_BUFFER, or as a pointer to a gss_buffer_desc object whose
length field contains the value zero." In iakerb_initiator_step(),
handle both cases when deciding whether to parse an acceptor message.
