Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

netfilter: synproxy: Fix out of bounds when parsing TCP options

The TCP option parser in synproxy (synproxy_parse_options) could read one byte out of bounds. When the length is 1, the execution flow gets into the loop, reads one byte of the opcode, and if the opcode is neither TCPOPT_EOL nor TCPOPT_NOP, it reads one more byte, which exceeds the length of 1.

This fix is inspired by commit 9609dad263f8 ("ipv4: tcp_input: fix stack out of bounds when parsing TCP options.").

v2 changes:

Added an early return when length < 0 to avoid calling skb_header_pointer with negative length.

Affected: Ubuntu:Pro:16.04:LTS: linux, Ubuntu:Pro:16.04:LTS: linux-aws, Ubuntu:Pro:16.04:LTS: linux-kvm

Demi Marie Obenour and Simon Gaiser discovered that several Xen para- virtualization device frontends did not properly restrict the access rights of device backends. An attacker could possibly use a malicious Xen backend to gain access to memory pages of a guest VM or cause a denial of service in the guest. (CVE-2022-23041)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Hardware crypto device drivers; - GPU drivers; - IIO subsystem; - Media drivers; - Network drivers; - SCSI subsystem; - SPI subsystem; - USB Gadget drivers; - Ceph distributed file system; - File systems infrastructure; - JFS file system; - Network file system (NFS) client; - Network file system (NFS) server daemon; - NILFS2 file system; - SMB network file system; - CAN network layer; - IPv6 networking; - MAC80211 subsystem; - Netfilter; - Netlink; - Network traffic control; - SCTP protocol; - TIPC protocol; (CVE-2024-46780, CVE-2021-47163, CVE-2024-46771, CVE-2021-47506, CVE-2024-36934, CVE-2024-35864, CVE-2024-26915, CVE-2021-47150, CVE-2024-50256, CVE-2024-53173, CVE-2024-53066, CVE-2024-53063, CVE-2021-47245, CVE-2024-26996, CVE-2024-56642, CVE-2021-47219, CVE-2024-56631, CVE-2021-47587, CVE-2021-47191, CVE-2023-52741, CVE-2021-46959, CVE-2024-26689, CVE-2024-26974, CVE-2024-56770, CVE-2024-56598, CVE-2024-49944, CVE-2024-5023…
