![]() ![]() 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.Ī Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in telemetry processing of Juniper Networks Junos OS allows a network-based authenticated attacker to flood the system with multiple telemetry requests, causing the Junos Kernel Debugging Streaming Daemon (jkdsd) process to crash, leading to a Denial of Service (DoS). ![]() This issue has been addressed in Redis versions 7.2.2, 7.0.14 and 6.2.14. This problem has existed since Redis 2.6.0-RC1. 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. On startup, Redis begins listening on a Unix socket before adjusting its permissions to the user-provided configuration. Redis is an in-memory database that persists on disk. With root access, an attacker can trigger a race condition that results in a fill_kobj_path out-of-bounds write. This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it.Īn issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers.
