Update to BIND 9.18.28

Security Fixes

A malicious DNS client that sent many queries over TCP but never read the responses could cause a server to respond slowly or not at all for other clients. This has been fixed. (CVE-2024-0760) [GL #4481]

It is possible to craft excessively large resource records sets, which have the effect of slowing down database processing. This has been addressed by adding a configurable limit to the number of records that can be stored per name and type in a cache or zone database. The default is 100, which can be tuned with the new max-records-per-type option. [GL #497] [GL #3405]

It is possible to craft excessively large numbers of resource record types for a given owner name, which has the effect of slowing down database processing. This has been addressed by adding a configurable limit to the number of records that can be stored per name and type in a cache or zone database. The default is 100, which can be tuned with the new max-types-per-name option. (CVE-2024-1737) [GL #3403]

ISC would like to thank Toshifumi Sakaguchi who independently discovered and responsibly reported the issue to ISC. [GL #4548]

Validating DNS messages signed using the SIG(0) protocol (RFC 2931) could cause excessive CPU load, leading to a denial-of-service condition. Support for SIG(0) message validation was removed from this version of named. (CVE-2024-1975) [GL #4480]

Due to a logic error, lookups that triggered serving stale data and required lookups in local authoritative zone data could have resulted in an assertion failure. This has been fixed. (CVE-2024-4076) [GL #4507]

Potential data races were found in our DoH implementation, related to HTTP/2 session object management and endpoints set object management after reconfiguration. These issues have been fixed. [GL #4473]

ISC would like to thank Dzintars and Ivo from nic.lv for bringing this to our attention.

When looking up the NS records of parent zones as part of looking up DS records, it was possible for named to trigger an assertion failure if serve-stale was enabled. This has been fixed. [GL #4661]

USN-6939-1: Exim vulnerability

Read Time:11 Second

Phillip Szelat discovered that Exim misparses multiline MIME header
filenames. A remote attacker could use this issue to bypass a MIME filename
extension-blocking protection mechanism and possibly deliver executable
attachments to the mailboxes of end users.

USN-6913-2: phpCAS vulnerability

Read Time:40 Second

USN-6913-1 fixed CVE-2022-39369 for Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.
This update provides the corresponding fix for Ubuntu 16.04 LTS.

Original advisory details:

Filip Hejsek discovered that phpCAS was using HTTP headers to determine
the service URL used to validate tickets. A remote attacker could
possibly use this issue to gain access to a victim’s account on a
vulnerable CASified service.

This security update introduces an incompatible API change. After applying
this update, third party applications need to be modified to pass in an
additional service base URL argument when constructing the client class.

For more information please refer to the section
“Upgrading 1.5.0 -> 1.6.0” of the phpCAS upgrading document:

USN-6938-1: Linux kernel vulnerabilities

Read Time:1 Minute, 39 Second

It was discovered that the device input subsystem in the Linux kernel did
not properly handle the case when an event code falls outside of a bitmap.
A local attacker could use this to cause a denial of service (system
crash). (CVE-2022-48619)

黄思聪 discovered that the NFC Controller Interface (NCI) implementation in
the Linux kernel did not properly handle certain memory allocation failure
conditions, leading to a null pointer dereference vulnerability. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-46343)

It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel when modifying certain settings values through debugfs.
A privileged local attacker could use this to cause a denial of service.
(CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device
volume management subsystem did not properly validate logical eraseblock
sizes in certain situations. An attacker could possibly use this to cause a
denial of service (system crash). (CVE-2024-25739)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

USN-6937-1: OpenSSL vulnerabilities

Read Time:54 Second

It was discovered that OpenSSL incorrectly handled TLSv1.3 sessions when
certain non-default TLS server configurations were in use. A remote
attacker could possibly use this issue to cause OpenSSL to consume
resources, leading to a denial of service. (CVE-2024-2511)

It was discovered that OpenSSL incorrectly handled checking excessively
long DSA keys or parameters. A remote attacker could possibly use this
issue to cause OpenSSL to consume resources, leading to a denial of
service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS.
(CVE-2024-4603)

William Ahern discovered that OpenSSL incorrectly handled certain memory
operations in a rarely-used API. A remote attacker could use this issue to
cause OpenSSL to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2024-4741)

Joseph Birr-Pixton discovered that OpenSSL incorrectly handled calling a
certain API with an empty supported client protocols buffer. A remote
attacker could possibly use this issue to obtain sensitive information, or
cause OpenSSL to crash, resulting in a denial of service. (CVE-2024-5535)

input it received through an API endpoint. An attacker with permission to
send requests to this endpoint could potentially inject arbitrary code.

On Ubuntu 20.04 LTS and Ubuntu 22.04 LTS, this vulnerability is only
present if the UI has been explicitly activated.
