Description

An authentication bypass vulnerability exists libcurl <8.0.0 in the connection reuse feature which can reuse previously established connections with incorrect user permissions due to a failure to check for changes in the CURLOPT_GSSAPI_DELEGATION option. This vulnerability affects krb5/kerberos/negotiate/GSSAPI transfers and could potentially result in unauthorized access to sensitive information. The safest option is to not reuse connections if the CURLOPT_GSSAPI_DELEGATION option has been changed.

Affected configurations

• haxx libcurl (>= 7.22.0 <= 7.88.1) • fedoraproject fedora 36 • debian debian linux 10.0 • netapp active iq unified manager • netapp h300s firmware • netapp h500s firmware • netapp h700s firmware • netapp h410s firmware • netapp ontap 9 • splunk universal forwarder (>= 8.2.0 < 8.2.12) • splunk universal forwarder (>= 9.0.0 < 9.0.6) • splunk universal forwarder 9.1.0
