Name of the Vulnerable Software and Affected Versions Redis versions 6.0 through 6.2.2 Redis versions 6.0 through 6.0.12

Description The issue is related to an integer overflow bug in Redis that can be exploited using the STRALGO LCS command to corrupt the heap and potentially result in remote code execution. This can allow a remote attacker to execute arbitrary code.

Recommendations For Redis versions 6.0 through 6.2.2, update to version 6.2.3 or later. For Redis versions 6.0 through 6.0.12, update to version 6.0.13 or later. As a temporary workaround, consider using ACL configuration to prevent clients from using the STRALGO LCS command until a patch is applied.
