Ubuntu Security Notice 5886-1 - Erik C. Bjorge discovered that some Intel Atom and Intel Xeon Scalable Processors did not properly implement access controls for out-of-band management. This may allow a privileged network-adjacent user to potentially escalate privileges. Cfir Cohen, Erdem Aktas, Felix Wilhelm, James Forshaw, Josh Eads, Nagaraju Kodalapura Nagabhushana Rao, Przemyslaw Duda, Liron Shacham and Ron Anderson discovered that some Intel Xeon Processors used incorrect default permissions in some memory controller configurations when using Intel Software Guard Extensions. This may allow a privileged local user to potentially escalate privileges.

Ubuntu Security Notice 5885-1 - Ronald Crane discovered integer overflow vulnerabilities in the Apache Portable Runtime that could potentially result in memory corruption. A remote attacker could possibly use these issues to cause a denial of service or execute arbitrary code.

In the Linux kernel 6.0.8, there is a use-after-free in ntfs_trim_fs in fs/ntfs3/bitmap.c.

In the Linux kernel 6.0.8, there is an out-of-bounds read in ntfs_attr_find in fs/ntfs/attrib.c.

In the Linux kernel 6.0.8, there is a use-after-free in inode_cgwb_move_to_attached in fs/fs-writeback.c, related to __list_del_entry_valid.

In the Linux kernel 6.0.8, there is a use-after-free in run_unpack in fs/ntfs3/run.c, related to a difference between NTFS sector size and media sector size.

In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure (for registering the sysctl table under a new location) during the renaming of a device.

Korenix JetWave 4200 Series 1.3.0 and JetWave 3200 Series 1.6.0 are vulnerable to Denial of Service via /goform/formDefault.

Ubuntu Security Notice 5884-1 - Kirill Tkhai discovered that the XFS file system implementation in the Linux kernel did not calculate size correctly when pre-allocating space in some situations. A local attacker could use this to expose sensitive information. Lee Jones discovered that a use-after-free vulnerability existed in the Bluetooth implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5882-1 - Gjoko Krstic discovered that DCMTK incorrectly handled buffers. If a user or an automated system were tricked into opening a certain specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 16.04 LTS. Omar Ganiev discovered that DCMTK incorrectly handled buffers. If a user or an automated system were tricked into opening a certain specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
