Lifecycle Timeline
1DescriptionNVD
Redis is an in-memory database that persists on disk. On startup, Redis begins listening on a Unix socket before adjusting its permissions to the user-provided configuration. If a permissive umask(2) is used, this creates a race condition that enables, during a short period of time, another process to establish an otherwise unauthorized connection. This problem has existed since Redis 2.6.0-RC1. This issue has been addressed in Redis versions 7.2.2, 7.0.14 and 6.2.14. Users are advised to upgrade. For users unable to upgrade, it is possible to work around the problem by disabling Unix sockets, starting Redis with a restrictive umask, or storing the Unix socket file in a protected directory.
AnalysisAI
Redis is an in-memory database that persists on disk. Rated low severity (CVSS 3.6). This Exposure of Resource to Wrong Sphere vulnerability could allow attackers to access resources from an unintended security context.
Technical ContextAI
This vulnerability is classified as Exposure of Resource to Wrong Sphere (CWE-668), which allows attackers to access resources from an unintended security context.

Affected products include: Redis, Fedoraproject Fedora, Debian Debian Linux.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Implement proper access controls, validate resource access permissions, use security boundaries.
