The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2122-1 advisory.
Redis is an in-memory database that persists on disk. Authenticated users can use string matching commands (like SCAN
or KEYS
) with a specially crafted pattern to trigger a denial-of-service attack on Redis, causing it to hang and consume 100% CPU time. The problem is fixed in Redis versions 6.0.18, 6.2.11, 7.0.9. (CVE-2022-36021)
Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted SRANDMEMBER
, ZRANDMEMBER
, and HRANDFIELD
commands can trigger an integer overflow, resulting in a runtime assertion and termination of the Redis server process. This problem affects all Redis versions.
Patches were released in Redis version(s) 6.0.18, 6.2.11 and 7.0.9. (CVE-2023-25155)
Redis is an open source, in-memory database that persists on disk. Authenticated users can use the HINCRBYFLOAT
command to create an invalid hash field that will crash Redis on access in affected versions. This issue has been addressed in in versions 7.0.11, 6.2.12, and 6.0.19. Users are advised to upgrade. There are no known workarounds for this issue. (CVE-2023-28856)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
