Debian LTS Advisory DLA-4682-1 [email protected]

Package : redis
Version : 5:7.0.15-1~deb12u8
CVE ID : CVE-2026-23631 CVE-2026-25243
It was discovered that there were two issues in Redis, the in-memory
key/value database:
CVE-2026-23631
An authenticated attacker could have exploited the master-replica
synchronization mechanism to trigger a use-after-free on replicas
where "replica-read-only" is disabled (or could be disabled),
which may have led to remote code execution. Installations that
prevent users from executing Lua scripts were unaffected.
CVE-2026-25243
The RESTORE command did not properly validate serialized values.
An authenticated attacker with permission to execute RESTORE
could have suppled a crafted serialized payload that triggers
invalid memory access and this could have led to remote code
execution.
For Debian 12 bookworm, these problems have been fixed in version
5:7.0.15-1~deb12u8.
We recommend that you upgrade your redis packages.
