Ubuntu Security Notice 6349-1 - Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service. Zi Fan Tan discovered that the binder IPC implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Microsoft on Wednesday revealed that a China-based threat actor known as Storm-0558 acquired the inactive consumer signing key to forging tokens to access Outlook by compromising an engineer’s corporate account. This enabled the adversary to access a debugging environment that contained a crash dump of the consumer signing system that took place in April 2021 and steal the key. “A consumer

After leaving many questions unanswered, a new post mortem from Microsoft explains the series of slip-ups that allowed attackers to steal and abuse a valuable cryptographic key.

Ubuntu Security Notice 6347-1 - William Zhao discovered that the Traffic Control subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service. It was discovered that the NTFS file system implementation in the Linux kernel did not properly check buffer indexes in certain situations, leading to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information.

Ubuntu Security Notice 6344-1 - Zi Fan Tan discovered that the binder IPC implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the f2fs file system in the Linux kernel, leading to a null pointer dereference vulnerability. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service.

Windows still suffers from issues related to the replacement of the system drive letter during impersonation. This can be abused to trick privilege processes to load configuration files and other resources from untrusted locations leading to elevation of privilege.

The Iranian threat actor tracked as APT34 has been linked to a new phishing attack that leads to the deployment of a variant of a backdoor called SideTwist. “APT34 has a high level of attack technology, can design different intrusion methods for different types of targets, and has supply chain attack capability,” NSFOCUS Security Labs said in a report published last week. APT34, also known by

Some foreign companies may be complying—potentially offering China’s spies hints for hacking their customers.
