![]() ![]() Reboots to restore services cannot be avoided once the memory leak begins. Due to internal anti-flood security controls and mechanisms reaching their maximum limit of response in the worst-case scenario, all affected Junos OS Evolved devices will reboot in as little as 1.5 days. Devices not vulnerable to the memory leak will process and forward the offending packet(s) to neighboring devices. As a DDoS event, the offending packets sent by the attacker will continue to flow from one device to another as long as they are received and processed by any devices, ultimately causing a cascading outage to any vulnerable devices. Once this condition begins, and as long as the attacker is able to sustain the offending traffic, a Distributed Denial of Service (DDoS) event occurs. This issue affects Juniper Networks Junos OS Evolved: 21.3 versions prior to 21.3R3-EVO 21.4 versions prior to 21.4R2-EVO 22.1 versions prior to 22.1R2-EVO 22.2 versions prior to 22.2R1-S1-EVO, 22.2R2-EVO.Īn Allocation of Resources Without Limits or Throttling weakness in the memory management of the Packet Forwarding Engine (PFE) on Juniper Networks Junos OS Evolved PTX10003 Series devices allows an adjacently located attacker who has established certain preconditions and knowledge of the environment to send certain specific genuine packets to begin a Time-of-check Time-of-use (TOCTOU) Race Condition attack which will cause a memory leak to begin. This is a race condition which is outside of an attackers direct control and it depends on system internal timing whether this issue occurs. In a Non Stop Routing (NSR) scenario, an unexpected kernel restart might be observed if "bgp auto-discovery" is enabled and if there is a BGP neighbor flap of auto-discovery sessions for any reason. drivers/tty/vcc.c has a race condition and resultant use-after-free if a physically proximate attacker removes a VCC device while calling open(), aka a race condition between vcc_open() and vcc_remove().Ī Use After Free vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). A user may be able to read arbitrary files as root.Īn issue was discovered in the Linux kernel through 6.2.0-rc2. This issue is fixed in watchOS 9.3, tvOS 16.3, macOS Ventura 13.2, iOS 16.3 and iPadOS 16.3. ![]() This vulnerability affects Firefox for Android FileName.Ī race condition was addressed with additional validation. Multiple race conditions in the font initialization could have led to memory corruption and execution of attacker-controlled code. Such a race condition could lead to implicit directory creation with permissions 0777 (without the sticky bit), which means that any low-privileged local user can delete and rename files inside those directories. The umask() call inside archive_write_disk_posix.c changes the umask of the whole process for a very short period of time a race condition with another thread can lead to a permanent umask 0 setting. Libarchive through 3.6.2 can cause directories to have world-writable permissions. ![]() The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/power/supply/da9150-charger.c if a physically proximate attacker unplugs a device. This vulnerability affects Firefox proto is set. These could have resulted in potentially exploitable use-after-free vulnerabilities. Race conditions in reference counting code were found through code inspection. Race Condition within a Thread in GitHub repository answerdev/answer prior to v1.1.1. ![]()
