krb5: MIT Kerberos 5 (krb5): Denial of Service via integer underflow and out-of-bounds read
A flaw was found in MIT Kerberos 5 krb5. An unauthenticated remote attacker can exploit an integer underflow and an out-of-bounds read vulnerability by calling gssacceptseccontext on a system with a NegoEx mechanism registered. This can lead to the process terminating, resulting in a Denial of...
CVE-2026-6479
Uncontrolled recursion in PostgreSQL SSL and GSS negotiation allows an attacker able to connect to a PostgreSQL AFUNIX socket to achieve sustained denial of service. If SSL and GSS are both disabled, an attacker can do the same via access to a PostgreSQL TCP socket. Versions before PostgreSQL 18....
CVE-2026-6479 PostgreSQL SSL/GSS init causes denial of service, via uncontrolled recursion
Uncontrolled recursion in PostgreSQL SSL and GSS negotiation allows an attacker able to connect to a PostgreSQL AFUNIX socket to achieve sustained denial of service. If SSL and GSS are both disabled, an attacker can do the same via access to a PostgreSQL TCP socket. Versions before PostgreSQL 18....
openssh: OpenSSH GSSAPI: Information disclosure or denial of service due to uninitialized variables
A flaw was found in the OpenSSH GSSAPI Generic Security Service Application Program Interface delta patches, as included in various Linux distributions. A remote attacker could exploit this by sending an unexpected GSSAPI message type during the key exchange process. This occurs because the...
golang.org/x/crypto/ssh: golang.org/x/crypto/ssh: Denial of Service via unbounded memory consumption in GSSAPI authentication
A flaw was found in golang.org/x/crypto/ssh. An attacker can exploit this vulnerability by sending specially crafted GSSAPI Generic Security Service Application Program Interface authentication requests to an SSH Secure Shell server. The server fails to validate the number of mechanisms specified...
