Denial Of Service (DoS)

gss-ntlmssp is vulnerable to Denial of Service DoS attacks. Multiple out-of-bounds reads when decoding NTLM fields can trigger a denial of service due to a 32-bit integer overflow condition and incorrect checks of consistency of length of internal buffers. This vulnerability can be triggered via...

Denial Of Service (DoS)

gss-ntlmssp is vulnerable to Denial of Service DoS attacks. Memory corruption can be triggered when decoding UTF16 strings if the variable 'outlen' is not initialized. This can lead to a denial of service if the write hits unmapped memory or randomly corrupts a byte in the application memory spac...

Denial Of Service (DoS)

gss-ntlmssp is vulnerable to Denial of Service DoS attacks. The length of the avpair is not checked properly for two elements, which can trigger an out-of-bounds read and cause a denial-of-service if memory is unmapped...
