Ubuntu Security Notice 6532-1 - Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain vector register instructions. A local attacker could use this to expose sensitive information. Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service.

A collection of 21 security flaws have been discovered in Sierra Wireless AirLink cellular routers and open-source software components like TinyXML and OpenNDS. Collectively tracked as Sierra:21, the issues expose over 86,000 devices across critical sectors like energy, healthcare, waste management, retail, emergency services, and vehicle tracking to cyber threats, according

Ubuntu Security Notice 6502-4 - Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem discovered that the InfiniBand RDMA driver in the Linux kernel did not properly check for zero-length STAG or MR registration. A remote attacker could possibly use this to execute arbitrary code. Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service.

Red Hat Security Advisory 2023-7557-01 - An update for kernel is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.4 Telecommunications Update Service, and Red Hat Enterprise Linux 8.4 Update Services for SAP Solutions. Issues addressed include information leakage and use-after-free vulnerabilities.

Red Hat Security Advisory 2023-7551-01 - An update for kernel-rt is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.4 Telecommunications Update Service, and Red Hat Enterprise Linux 8.4 Update Services for SAP Solutions. Issues addressed include information leakage and use-after-free vulnerabilities.

Ubuntu Security Notice 6502-2 - Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem discovered that the InfiniBand RDMA driver in the Linux kernel did not properly check for zero-length STAG or MR registration. A remote attacker could possibly use this to execute arbitrary code. Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service.

Red Hat Security Advisory 2023-7513-01 - An update for linux-firmware is now available for Red Hat Enterprise Linux 7. Issues addressed include an information leakage vulnerability.

An arbitrary file creation vulnerability exists in the Javascript exportDataObject API of Foxit Reader 12.1.3.15356 due to mistreatment of whitespace characters. A specially crafted malicious file can create files at arbitrary locations, which can lead to arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

Ubuntu Security Notice 6503-1 - Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service. Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service or possibly execute arbitrary code.
