openSUSE 16 Security Update : redis (openSUSE-SU-2026:21612-1)

high Nessus Plugin ID 339035

Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21612-1 advisory.

Changes in redis:

- Update to 8.10.1

Update urgency: SECURITY: There are security fixes in the release.

- Security fixes
- (CVE-2026-62356) Miscalculated buffer size in CMSketch RDB loading may lead to heap OOB write
- Out-of-bounds access in TopK heap cleanup path (MOD-15410)
- Use-after-free in the TLS pending-data list when a command closes another pending connection
- A malicious RDB payload with an out-of-range SLOT_INFO slot id causes memory corruption during RDB loading, which may lead to Remote Code Execution
- Vector Sets: missing node level validation when loading a vector set from RDB may lead to out-of-bounds access
- Vector Sets: use-after-free when VREM mutates the HNSW graph while background VSIM threads are still running
- Vector Sets: a negative hnsw_search() return was treated as a huge unsigned count, reading past the end of the result arrays
- TLS client certificate authentication bypass: a Common Name containing an embedded NUL byte was truncated, allowing a client to authenticate as another (possibly privileged) ACL user
- #15594 Use-after-free in the blocked-client list when reprocessing a command evicts another client blocked on the same key

- Restrict the modules flavour to x86_64 and aarch64 -- RedisBloom and RedisTimeSeries abort on anything else with only supports 64-bit architectures (x64, arm64v8), redisjson's vendored redis-module is 64-bit only, and modules/common.mk maps no other architecture at all

- Update to 8.10.0
