CVE-2023-25563 GSS-NTLMSSP vulnerable to multiple out-of-bounds reads when decoding NTLM fields

GSS-NTLMSSP is a mechglue plugin for the GSSAPI library that implements NTLM authentication. 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...

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...
