Description

A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This may allow an attacker with enough access to retrieve the password from the memory.

Affected configurations

• shadow-maint shadow-utils (< 4.14.0) • redhat codeready linux builder 8.0 • redhat codeready linux builder 9.0 • redhat codeready linux builder for arm64 8.0 aarch64 • redhat codeready linux builder for arm64 9.0 aarch64 • redhat codeready linux builder for ibm z systems 8.0 s390x • redhat codeready linux builder for ibm z systems 9.0 s390x • redhat codeready linux builder for power little endian 8.0 ppc64le • redhat codeready linux builder for power little endian 9.0 ppc64le • redhat enterprise linux 8.0 • redhat enterprise linux 9.0 • redhat enterprise linux for arm 64 8.0 • redhat enterprise linux for arm 64 9.0 • redhat enterprise linux for ibm z systems 8.0 s390x • redhat enterprise linux for ibm z systems 9.0 s390x • redhat enterprise linux for power little endian 8.0 ppc64le • redhat enterprise linux for power little endian 9.0 ppc64le
