Summary
samba vulnerabilities
Details

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)

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)

Florent Saudel discovered that Samba incorrectly handled certain Spotlight requests. A remote attacker could possibly use this issue to cause Samba to consume resources, leading to a denial of service. (CVE-2023-34966)
