Hi all,

Squid 7.6 release contains fixes for and releases the embargo on
CVE-2026-47729 and CVE-2026-50012.


Apologies, this first one (CVE-2026-47729) embargo is over, but the fix will
actually be in Squid 7.7.


CVE-2026-47729

Due to a Improper Validation of Syntactic Correctness of Input
bug, Squid is vulnerable to a Out-of-bounds Read
attack against the FTP gateway.

This problem allows a trusted client to perform an Out-of-Bounds
Read from random unrelated transactions when accessing a
misbehaving FTP server through Squid's gateway feature.

I'm slightly confused about this. The referenced fix is in 7.6. Can
you point us to the correct fix in 7.7 for CVE-2026-47729?

At least
https://github.com/squid-cache/squid/commit/865a131c7d557e68c965043d98c2eccae26deef8
matches as well the followup from Alan.
