maint-0.2.7-redux is an attempt to try to re-create a plausible
maint-0.2.7 branch. I've started from the tor-0.2.7.6, and then I
merged maint-0.2.6 into the branch.
This has produced 2 conflicts: one related to the
rendcommon->rendcache move, and one to the authority refactoring.
The length of auth_data from an INTRODUCE2 cell is checked when the
auth_type is recognized (1 or 2), but not for any other non-zero
auth_type. Later, auth_data is assumed to have at least
REND_DESC_COOKIE_LEN bytes, leading to a client-triggered out of bounds
read.
Fixed by checking auth_len before comparing the descriptor cookie
against known clients.
Fixes#15823; bugfix on 0.2.1.6-alpha.
This helps protect against bugs where any part of a buf_t's memory
is passed to a function that expects a NUL-terminated input.
It also closes TROVE-2016-10-001 (aka bug 20384).
In get_token(), we could read one byte past the end of the
region. This is only a big problem in the case where the region
itself is (a) potentially hostile, and (b) not explicitly
nul-terminated.
This patch fixes the underlying bug, and also makes sure that the
one remaining case of not-NUL-terminated potentially hostile data
gets NUL-terminated.
Fix for bug 21018, TROVE-2016-12-002, and CVE-2016-1254
There was a dead check when we made sure that an array member of a
struct was non-NULL. Tor has been doing this check since at least
0.2.3, maybe earlier.
Fixes bug 17781.
Previously we'd suppressed the mask-bits field in the output when
formatting a policy if it was >=32. But that should be a >=128 if
we're talking about IPv6.
Since we didn't put these in descriptors, this bug affects only log
messages and controller outputs.
Fix for bug 16056. The code in question was new in 0.2.0, but the
bug was introduced in 0.2.4 when we started supporting IPv6 exits.
The tor_cert_get_checkable_sig function uses the signing key included in
the certificate (if available) when a separate public key is not given.
When the signature is valid, the tor_cert_checksig function copies the
public key from the checkable structure to the public key field of the
certificate signing key.
In situations where the separate public key is not given but the
certificate includes a signing key, the source and destination pointers
in the copy operation are equal and invoke undefined behavior.
Undefined behaviour is avoided by ensuring both pointers are different.
The wrong list was used when looking up expired intro points in a rend
service object causing what we think could be reachability issues and
triggering a BUG log.
Fixes#16702

BSD make takes spaces around = literally
and produces a "TESTING_TOR_BINARY "
variable with a trailing space, which leads
to test_keygen.sh failure.
Fixes 17154
When we find a conflict in the keypinning journal, treat the new
entry as superseding all old entries that overlap either of its
keys.
Also add a (not-yet-used) configuration option to disable keypinning
enforcement.
src/test/test_policy.c:
Merged calls to policies_parse_exit_policy by adding additional arguments.
fixup to remaining instance of ~EXIT_POLICY_IPV6_ENABLED.
Compacting logic test now produces previous list length of 4, corrected this.
src/config/torrc.sample.in:
src/config/torrc.minimal.in-staging:
Merged torrc modification dates in favour of latest.
