Two patches, on 6.6 and 6.7:

- on for the libX11:
Quote:
Malformed messages can cause heap corruption in the X Input Method
client implementation in libX11.
- the other for X server:
Quote:
Pixmaps inside the xserver were an info leak.
Prefere to restart the X server or your used x11 client.

A new patch, this time for the libSSL, on 6.7:

The TLSv1.3 client could hang, crash, leak memory or not interoperate
with some TLSv1.3 servers.

Excuse-me. I forgot to publish here!

----

two days ago a new patch has been released, about mmap, only 6.7.

Quote:
mmap can exhaust kernel memory for PROT_NONE MAP_SHARED mappings.
Reboot the machine, because affects the kernel ;-)

The first two patches for 6.8 have appeared on the mirrors. Something went wrong, it would seem, when the signature files SHA256 and SHA256.sig were created. The extra trailing newline character seems to confuse signify:
Code:

Signature Verified

syspatch68-002_icmp6.tgz: OK
signify: unable to parse checksum line
Seems a bit sloppy tbh. Also the first patch appeared yesterday dated (tomorrow) two days into the future.
