Rocky Linux 8 : redis:6 (RLSA-2021:2034)
high Nessus Plugin ID 157734
Synopsis
The remote Rocky Linux host is missing a security update.Description
The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2021:2034 advisory.- Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. An integer overflow bug in Redis version 6.0 or newer could be exploited using the `STRALGO LCS` command to corrupt the heap and potentially result with remote code execution. The problem is fixed in version 6.2.3 and 6.0.13. An additional workaround to mitigate the problem without patching the redis-server executable is to use ACL configuration to prevent clients from using the `STRALGO LCS` command. (CVE-2021-29477)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
