The remote Oracle Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2023-3097 advisory. - Fix CVE-2023-25563: multiple out-of-bounds read when decoding NTLM fields - Fix CVE-2023-25564: memory corruption when decoding UTF16 strings - Fix...

CVE-2023-25566

A flaw was found in GSS-NTLMSSP, a mechglue plugin for the GSSAPI library that implements NTLM authentication. A memory leak can be triggered when parsing usernames, triggering a denial of service. The domain portion of a username may be overridden, causing an allocated memory area the size of th...

CVE-2023-25565

A flaw was found in GSS-NTLMSSP, a mechglue plugin for the GSSAPI library that implements NTLM authentication. An incorrect free when decoding target information can trigger a denial of service. The error condition incorrectly assumes the cb and sh buffers contain a copy of the data that needs to...

CVE-2023-25567

GSS-NTLMSSP, a mechglue plugin for the GSSAPI library that implements NTLM authentication, has an out-of-bounds read when decoding target information prior to version 1.2.0. The length of the avpair is not checked properly for two of the elements which can trigger an out-of-bound read. The...

GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. Prior to version 1.2.0, an incorrect free when decoding target information can trigger a denial of service. The error condition incorrectly assumes the cb and sh buffers contain a copy of the data that...

CVE-2023-25564

The CVE-2023-25564 issue affects GSS-NTLMSSP (NTLM support for GSSAPI). Before version 1.2.0, decoding UTF-16 strings could leave outlen uninitialized, causing a potential out-of-bounds write and memory corruption that may trigger a denial of service via gss_accept_sec_context. The advisory state...

CVE-2023-25563

CVE-2023-25563 affects the GSS-NTLMSSP mechglue for the GSSAPI library. The vulnerability arises from multiple out-of-bounds reads when decoding NTLM fields and a 32-bit integer overflow that can cause improper length checks of internal buffers. If an application accepts NTLM tokens longer than 4...
