Subject: [PATCH] Bug 5378: type mismatch in libTrie (#1830)
|
|
|
|
TrieNode::add() incorrectly computed an offset of an internal data
|
|
structure, resulting in out-of-bounds memory accesses that could cause
|
|
corruption or crashes.
|
|
|
|
This bug was discovered and detailed by Joshua Rogers at
|
|
https://megamansec.github.io/Squid-Security-Audit/esi-underflow.html
|
|
where it was filed as "Buffer Underflow in ESI".
|
|
|
|
CVE: CVE-2024-37894
|
|
Upstream-Status: Backport [https://github.com/squid-cache/squid/commit/920563e7a080155fae3ced73d6198781e8b0ff04]
