CVE-2019-10193
CVSS v2.0
9.0
High
| Vector | AV:N/AC:L/Au:S/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Redis versions 3.x before 3.2.13
Redis versions 4.x before 4.0.14
Redis versions 5.x before 5.0.4
Description
The issue is related to a stack-buffer overflow vulnerability in the Redis hyperloglog data structure. It occurs when the SETRANGE command corrupts the hyperloglog data structure, allowing an attacker to add up to 12 bytes of information past the end of a stack-allocated buffer. This can be exploited by a remote attacker to compromise data integrity, gain unauthorized access to sensitive information, and cause a denial of service.
Recommendations
For Redis versions 3.x before 3.2.13, update to version 3.2.13 or later.
For Redis versions 4.x before 4.0.14, update to version 4.0.14 or later.
For Redis versions 5.x before 5.0.4, update to version 5.0.4 or later.
As a temporary workaround, consider restricting the use of the SETRANGE command to minimize the risk of exploitation.
