Prior to version 1.2.0, multiple out-of-bounds reads when decoding NTLM fields can trigger a denial of service. A 32-bit integer overflow condition can lead to incorrect checks of consistency of length of internal buffers. Although most applications will error out before accepting a singe input buffer of 4GB in length this could theoretically happen. This vulnerability can be triggered via the main `gss_accept_sec_context` entry point if the application allows tokens greater than 4GB in length. This can lead to a large, up to 65KB, out-of-bounds read which could cause a denial-of-service if it reads from unmapped memory. Version 1.2.0 contains a patch for the out-of-bounds reads."}],"source":{"advisory":"GHSA-jjjx-5qf7-9mgf","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T11:25:19.176Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-jjjx-5qf7-9mgf","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/gssapi/gss-ntlmssp/security/advisories/GHSA-jjjx-5qf7-9mgf"},{"name":"https://github.com/gssapi/gss-ntlmssp/commit/97c62c6167299028d80765080e74d91dfc99efbd","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/gssapi/gss-ntlmssp/commit/97c62c6167299028d80765080e74d91dfc99efbd"},{"name":"https://github.com/gssapi/gss-ntlmssp/releases/tag/v1.2.0","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/gssapi/gss-ntlmssp/releases/tag/v1.2.0"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-03-10T20:57:41.972079Z","id":"CVE-2023-25563","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-03-10T21:12:07.826Z"}}]}}
