Potential Incompatibilities #
- OTP-18897
-
- Application(s):
- ssh
With this change (being response to CVE-2023-48795), ssh can negotiate "strict KEX" OpenSSH extension with peers supporting it; also 'chacha20-poly1305@openssh.com' algorithm becomes a less preferred cipher.
If strict KEX availability cannot be ensured on both connection sides, affected encryption modes(CHACHA and CBC) can be disabled with standard ssh configuration. This will provide protection against vulnerability, but at a cost of affecting interoperability. See Configuring algorithms in SSH.
OTP-24.3.4.15 #
- OTP-18896
-
- Application(s):
- otp
Updated copyright and license information.
asn1-5.0.18.2 #
The asn1-5.0.18.2 application can be applied independently of other applications on a full OTP 24 installation.
- OTP-18844
-
- Application(s):
- asn1
Fix benign warning from gcc 11 about mismatching call to free().
Full runtime dependencies of asn1-5.0.18.2: erts-11.0, kernel-7.0, stdlib-3.13
erl_interface-5.2.2.1 #
The erl_interface-5.2.2.1 application can be applied independently of other applications on a full OTP 24 installation.
- OTP-18877
-
- Application(s):
- erl_interface, erts
Replaced old md5 implementation with an implementation from OpenSSL.
erts-12.3.2.15 #
Note! The erts-12.3.2.15 application *cannot* be applied independently of other applications on an arbitrary OTP 24 installation. On a full OTP 24 installation, also the following runtime dependency has to be satisfied: -- kernel-8.3 (first satisfied in OTP 24.3)
- OTP-18802
-
- Application(s):
- erts
Fix faulty debug assert when page size is larger than 16kb, like on PowerPC. Did crash debug VM directly at start.
- OTP-18885
-
On OTP 24 and OTP 25, incoming distributed messages larger than 64 KiB sent using an alias leaked memory if the alias had been removed prior to entering the node. This issue was not present on OTP 26.
Incoming distributed messages larger than 64 KiB sent using an alias which had been removed on the receiving node could crash the node. This crash was quite unlikely on OTP 24 and OTP 25, but very likely on OTP 26.
'DOWN' signals with exit reason larger than 64 KiB directed towards a process on a node with a not matching creation leaked memory on the receiving node. Such signals should however be very rare.
- OTP-18902
-
- Application(s):
- erts
Removed unnecessary PCRE source tar-ball.
- OTP-18830
-
- Application(s):
- erts
- Related Id(s):
- PR-7823
Removed unnecessary regexp library used when generating yielding BIFs.
- OTP-18877
-
- Application(s):
- erl_interface, erts
Replaced old md5 implementation with an implementation from OpenSSL.
- OTP-18899
-
- Application(s):
- erts
Removed unused makewhatis script.
Full runtime dependencies of erts-12.3.2.15: kernel-8.3, sasl-3.3, stdlib-3.13
mnesia-4.20.4.4 #
The mnesia-4.20.4.4 application can be applied independently of other applications on a full OTP 24 installation.
- OTP-18850
-
- Application(s):
- mnesia
mnesia:add_table_copy/3 no longer fails with reason system_limit when the node is starting.
Full runtime dependencies of mnesia-4.20.4.4: erts-9.0, kernel-5.3, stdlib-3.4
ssh-4.13.2.4 #
The ssh-4.13.2.4 application can be applied independently of other applications on a full OTP 24 installation.
- OTP-18869
-
With this change, connection handler does not execute socket operations until it becomes socket owner. Previously errors could occur if connection handler tried to work with socket whose owner exited.
- OTP-18897

- Application(s):
- ssh
