Redis · Redis · CVE-2021-29477
**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.
