March 8, 2023

Read Time:1 Minute, 21 Second

Evgeny Legerov discovered that Samba incorrectly handled buffers in
certain GSSAPI routines of Heimdal. A remote attacker could possibly use
this issue to cause Samba to crash, resulting in a denial of service.
(CVE-2022-3437)

Tom Tervoort discovered that Samba incorrectly used weak rc4-hmac Kerberos
keys. A remote attacker could possibly use this issue to elevate
privileges. (CVE-2022-37966, CVE-2022-37967)

It was discovered that Samba supported weak RC4/HMAC-MD5 in NetLogon Secure
Channel. A remote attacker could possibly use this issue to elevate
privileges. (CVE-2022-38023)

Greg Hudson discovered that Samba incorrectly handled PAC parsing. On
32-bit systems, a remote attacker could use this issue to escalate
privileges, or possibly execute arbitrary code. (CVE-2022-42898)

Joseph Sutton discovered that Samba could be forced to issue rc4-hmac
encrypted Kerberos tickets. A remote attacker could possibly use this issue
to escalate privileges. This issue only affected Ubuntu 20.04 LTS and
Ubuntu 22.04 LTS. (CVE-2022-45141)

WARNING: This update upgrades the version of Samba to 4.15.13. Please see
the upstream release notes for important changes in the new version:

https://www.samba.org/samba/history/samba-4.15.0.html

In addition, the security fixes included in this new version introduce
several important behavior changes which may cause compatibility problems
interacting with systems still expecting the former behavior. Please see

Hard-coded secrets up 67% as secrets sprawl threatens software supply chain

March 8, 2023

Read Time:35 Second

The number of detected hard-coded secrets increased by 67% last year compared to 2021, with 10 million new secrets discovered in public GitHub commits in 2022. That’s according to GitGuardian’s State of Secrets Sprawl 2023 report. It found that hard-coded secrets and accelerating secrets sprawl (storing secrets in many different places) are threatening the security of software supply chains.

Hard-coded secrets pose significant security risks because they are often stored in plain text, making it easier for attackers to extract them from source code. They can also be inadvertently disclosed or exposed through other security vulnerabilities like code injection or data leaks.
