Packet Storm

Red Hat Security Advisory 2023-5964-01 - An update for collectd-libpod-stats is now available for Red Hat OpenStack Platform 16.2.5. Issues addressed include a denial of service vulnerability.

Red Hat Security Advisory 2023-5715-01 - An update for the nginx:1.20 module is now available for Red Hat Enterprise Linux 8.6 Extended Update Support. Issues addressed include a denial of service vulnerability.

Red Hat Security Advisory 2023-5712-01 - An update for the nginx:1.20 module is now available for Red Hat Enterprise Linux 8. Issues addressed include a denial of service vulnerability.

Red Hat Security Advisory 2023-5701-01 - An update is now available for Red Hat Ansible Automation Platform 2.3. Issues addressed include a denial of service vulnerability.

PowerVR suffers from a multitude of memory management bugs including out-of-bounds access and information leakage.

VIMESA VHF/FM Transmitter Blue Plus version 9.7.1 suffers from a denial of service vulnerability. An unauthenticated attacker can issue an unauthorized HTTP GET request to the unprotected endpoint doreboot and restart the transmitter operations.

Ubuntu Security Notice 6440-2 - Seth Jenkins discovered that the Linux kernel did not properly perform address randomization for a per-cpu memory management structure. A local attacker could use this to expose sensitive information or in conjunction with another kernel vulnerability. It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service.

Debian Linux Security Advisory 5527-2 - The webkit2gtk update released as 5527-1 introduced a regression that is causing programs such as yelp, liferea or gnucash to stop working in certain cases.

Ubuntu Security Notice 6445-1 - It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. Daniel Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorised memory reads via a speculative side-channel attack. A local attacker could use this to expose sensitive information, including kernel memory.

Ubuntu Security Notice 6446-1 - Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service or possibly execute arbitrary code. 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.
