USN-6237-1 fixed several vulnerabilities in curl. This update provides the
corresponding updates for Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, and
Ubuntu 18.04 LTS.

Original advisory details:

Hiroki Kurosawa discovered that curl incorrectly handled validating certain
certificate wildcards. A remote attacker could possibly use this issue to
spoof certain website certificates using IDN hosts. (CVE-2023-28321)

Hiroki Kurosawa discovered that curl incorrectly handled callbacks when
certain options are set by applications. This could cause applications
using curl to misbehave, resulting in information disclosure, or a denial
of service. (CVE-2023-28322)

It was discovered that curl incorrectly handled saving cookies to files. A
local attacker could possibly use this issue to create or overwrite files.
This issue only affected Ubuntu 22.10, and Ubuntu 23.04. (CVE-2023-32001)

A vulnerability has been discovered in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) software that could allow for unauthorized access. Cisco Adaptive Security Appliance (ASA) Software is the core operating system for the Cisco ASA Family. It delivers enterprise-class firewall capabilities for ASA devices in an array of form factors for any distributed network environment. Cisco Firepower Threat Defense (FTD) Software is an integrative software image combining CISCO ASA and Firepower feature into one hardware and software inclusive system to assist in flagging specific network traffic patterns, create alerts and better control your network. An attacker could exploit this vulnerability by specifying a default connection profile/tunnel group while conducting a brute force attack or while establishing a clientless SSL VPN session using valid credentials. Utilizing the brute force attack to obtain valid credentials, an attacker could use this to establish unauthorized VPN sessions and then install ransomware.

USN-6164-1 fixed several vulnerabilities in c-ares. This update provides
the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

Original advisory details:

Hannes Moesl discovered that c-ares incorrectly handled certain ipv6
addresses. An attacker could use this issue to cause c-ares to crash,
resulting in a denial of service, or possibly execute arbitrary code.
(CVE-2023-31130)

Xiang Li discovered that c-ares incorrectly handled certain UDP packets. A
remote attacker could possibly use this issue to cause c-res to crash,
resulting in a denial of service. (CVE-2023-32067)

Daniel Moghimi discovered that some Intel(R) Processors did not properly
clear microarchitectural state after speculative execution of various
instructions. A local unprivileged user could use this to obtain to
sensitive information. (CVE-2022-40982)

Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did
not properly perform permissions checks when handling HCI sockets. A
physically proximate attacker could use this to cause a denial of service
(bluetooth communication). (CVE-2023-2002)

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. (CVE-2023-20593)

Zi Fan Tan discovered that the binder IPC implementation in the Linux
kernel contained a use-after-free vulnerability. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2023-21255)

Juan Jose Lopez Jaimez, Meador Inge, Simon Scannell, and Nenad Stojanovski
discovered that the BPF verifier in the Linux kernel did not properly mark
registers for precision tracking in certain situations, leading to an out-
of-bounds access vulnerability. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-2163)

Zheng Zhang discovered that the device-mapper implementation in the Linux
kernel did not properly handle locking during table_clear() operations. A
local attacker could use this to cause a denial of service (kernel
deadlock). (CVE-2023-2269)

It was discovered that the DVB Core driver in the Linux kernel did not
properly handle locking events in certain situations. A local attacker
could use this to cause a denial of service (kernel deadlock).
(CVE-2023-31084)

It was discovered that the kernel->user space relay implementation in the
Linux kernel did not properly perform certain buffer calculations, leading
to an out-of-bounds read vulnerability. A local attacker could use this to
cause a denial of service (system crash) or expose sensitive information
(kernel memory). (CVE-2023-3268)

It was discovered that the video4linux driver for Philips based TV cards in
the Linux kernel contained a race condition during device removal, leading
to a use-after-free vulnerability. A physically proximate attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2023-35823)

It was discovered that the SDMC DM1105 PCI device driver in the Linux
kernel contained a race condition during device removal, leading to a use-
after-free vulnerability. A physically proximate attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2023-35824)

It was discovered that the Renesas USB controller driver in the Linux
kernel contained a race condition during device removal, leading to a use-
after-free vulnerability. A privileged attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-35828)

It was discovered that the universal 32bit network packet classifier
implementation in the Linux kernel did not properly perform reference
counting in some situations, leading to a use-after-free vulnerability. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2023-3609)

It was discovered that the Quick Fair Queueing network scheduler
implementation in the Linux kernel contained an out-of-bounds write
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-3611)

It was discovered that the network packet classifier with
netfilter/firewall marks implementation in the Linux kernel did not
properly handle reference counting, leading to a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-3776)
