Ubuntu Security Notice 5538-1 - It was discovered that libtirpc incorrectly handled certain inputs. An attacker could possibly use this issue to cause a denial of service.

IBM PowerVM VIOS 3.1 could allow a remote attacker to tamper with system configuration or cause a denial of service. IBM X-Force ID: 230956.

In Eclipse Californium version 2.0.0 to 2.7.2 and 3.0.0-3.5.0 a DTLS resumption handshake falls back to a DTLS full handshake on a parameter mismatch without using a HelloVerifyRequest. Especially, if used with certificate based cipher suites, that results in message amplification (DDoS other peers) and high CPU load (DoS own peer). The misbehavior occurs only with DTLS_VERIFY_PEERS_ON_RESUMPTION_THRESHOLD values larger than 0.

The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges.

Details have been shared about a security vulnerability in Dahua's Open Network Video Interface Forum (ONVIF) standard implementation, which, when exploited, can lead to seizing control of IP cameras.  Tracked as CVE-2022-30563 (CVSS score: 7.4), the "vulnerability could be abused by attackers to compromise network cameras by sniffing a previous unencrypted ONVIF interaction and replaying the

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment.\n\nAffected versions of this package are vulnerable to Prototype Pollution. The `Schema.path()` function is vulnerable to prototype pollution when setting the schema object. This vulnerability allows modification of the Object prototype and could be manipulated into a Denial of Service (DoS) attack.

PicoC v3.2.2 was discovered to contain a NULL pointer dereference at variable.c.

Honeywell Experion PKS Safety Manager 5.02 has Insufficient Verification of Data Authenticity. According to FSCT-2022-0054, there is a Honeywell Experion PKS Safety Manager unauthenticated firmware update issue. The affected components are characterized as: Firmware update functionality. The potential impact is: Firmware manipulation. The Honeywell Experion PKS Safety Manager utilizes the DCOM-232/485 communication FTA serial interface and Enea POLO bootloader for firmware management purposes. An engineering workstation running the Safety Builder software communicates via serial or serial-over-ethernet link with the DCOM-232/485 interface. Firmware images were found to have no authentication (in the form of firmware signing) and only relied on insecure checksums for regular integrity checks. Firmware images are unsigned. An attacker with access to the serial interface (either through physical access, a compromised EWS or an exposed serial-to-ethernet gateway) can utilize hardcoded cred...

Ubuntu Security Notice 5535-1 - Joseph Nuzman discovered that some Intel processors did not properly initialise shared resources. A local attacker could use this to obtain sensitive information. Mark Ermolov, Dmitry Sklyarov and Maxim Goryachy discovered that some Intel processors did not prevent test and debug logic from being activated at runtime. A local attacker could use this to escalate privileges.

An issue was discovered in Veritas NetBackup 8.1.x through 8.1.2, 8.2, 8.3.x through 8.3.0.2, 9.x through 9.0.0.1, and 9.1.x through 9.1.0.1 (and related NetBackup products). An attacker with unprivileged local access to a Windows NetBackup Primary server could potentially escalate their privileges.
