CVE-2009-3295 1 Mit 1 Kerberos 5 2026-04-23 N/A
The prep_reprocess_req function in kdc/do_tgs_req.c in the cross-realm referral implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.7 before 1.7.1 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a ticket request.
CVE-2009-4212 2 Mit, Redhat 4 Kerberos, Kerberos 5, Enterprise Linux and 1 more 2026-04-23 N/A
Multiple integer underflows in the (1) AES and (2) RC4 decryption functionality in the crypto library in MIT Kerberos 5 (aka krb5) 1.3 through 1.6.3, and 1.7 before 1.7.1, allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code by providing ciphertext with a length that is too short to be valid.
CVE-2007-5971 3 Apple, Mit, Redhat 4 Mac Os X, Mac Os X Server, Kerberos 5 and 1 more 2026-04-23 N/A
Double free vulnerability in the gss_krb5int_make_seal_token_v3 function in lib/gssapi/krb5/k5sealv3.c in MIT Kerberos 5 (krb5) has unknown impact and attack vectors.
CVE-2007-0956 4 Canonical, Debian, Mit and 1 more 4 Ubuntu Linux, Debian Linux, Kerberos 5 and 1 more 2026-04-23 N/A

CVE-2007-5902 1 Mit 1 Kerberos 5 2026-04-23 N/A
Integer overflow in the svcauth_gss_get_principal function in lib/rpc/svc_auth_gss.c in MIT Kerberos 5 (krb5) allows remote attackers to have an unknown impact via a large length value for a GSS client name in an RPC request.
CVE-2008-0948 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-04-23 N/A
Buffer overflow in the RPC library (lib/rpc/rpc_dtablesize.c) used by libgssrpc and kadmind in MIT Kerberos 5 (krb5) 1.2.2, and probably other versions before 1.3, when running on systems whose unistd.h does not define the FD_SETSIZE macro, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by triggering a large number of open file descriptors.

The (1) ftpd and (2) ksu programs in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, and (b) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which might allow local users to gain privileges by causing setuid to fail to drop privileges.
