commit 8fcff9c09824b18628f010d26a04247f6a6cbcb8
Author: Alex Rousskov <rousskov@measurement-factory.com>
Date: Sun Nov 12 09:33:20 2023 +0000
Do not update StoreEntry expiration after errorAppendEntry() (#1580)
errorAppendEntry() is responsible for setting entry expiration times,
which it does by calling StoreEntry::storeErrorResponse() that calls
StoreEntry::negativeCache().
This change was triggered by a vulnerability report by Joshua Rogers at
https://megamansec.github.io/Squid-Security-Audit/cache-uaf.html where
it was filed as "Use-After-Free in Cache Manager Errors". The reported
"use after free" vulnerability was unknowingly addressed by 2022 commit
1fa761a that removed excessively long "reentrant" store_client calls
responsible for the disappearance of the properly locked StoreEntry in
this (and probably other) contexts.
