CVE-2024-37371: n/a
In MIT Kerberos 5 (aka krb5) before 1.21.3, an attacker can cause invalid memory reads during GSS message token handling by sending message tokens with invalid length fields.
AI Analysis
Technical Summary
CVE-2024-37371 affects MIT Kerberos 5 (krb5) prior to version 1.21.3. The issue arises during the handling of GSS message tokens, where an attacker can craft tokens with invalid length fields that cause the software to perform invalid memory reads. This vulnerability can result in a denial of service condition by crashing the affected process. The CVSS v3.1 score is 9.1 (critical), reflecting network attack vector, low complexity, no privileges required, no user interaction, unchanged scope, high confidentiality impact, no integrity impact, and high availability impact.
Potential Impact
Successful exploitation allows an unauthenticated remote attacker to cause invalid memory reads, leading to denial of service (application crash). There is a high impact on confidentiality and availability, but no impact on integrity. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Upgrade MIT Kerberos 5 to version 1.21.3 or later, where this vulnerability is fixed. Patch status is confirmed by the version boundary provided. No other mitigation or workaround is indicated.
