clean_client() in lib/rpc/svc_auth_gssapi.c in MIT Kerberos 5 (aka krb5) restarts its scan from the head of the client list after each removal, resulting in quadratic CPU cost. Remote attackers can cause a denial of service (CPU consumption in kadmind) by accumulating a large number of AUTH_GSSAPI client entries.
The AUTH_GSSAPI handler in lib/rpc/svc_auth_gssapi.c in MIT Kerberos 5 (aka krb5) does not free decoded arguments on certain error paths, which allows remote attackers to cause a denial of service (memory exhaustion in kadmind) via crafted AUTH_GSSAPI_INIT requests that trigger authentication failures.
The GSS-RPC transport layer in MIT Kerberos 5 (aka krb5) 1.4 and later does not release the previous authentication context when a client switches from an RPCSEC_GSS or AUTH_GSSAPI flavor to a non-GSS flavor on the same TCP connection. This allows remote attackers to cause a denial of service (memory exhaustion in kadmind) by repeatedly establishing and abandoning GSS authentication contexts.
The GSS-RPC layer in MIT Kerberos 5 (aka krb5) does not enforce size limits on XDR-decoded data, which allows remote authenticated users to cause a denial of service (memory exhaustion or excessive CPU consumption in kadmind) via crafted RPC requests that trigger unbounded memory allocations during XDR decoding.
The policy RPC stubs in kadmin/server/server_stubs.c in MIT Kerberos 5 (aka krb5) 1.5.3 and later do not reject a NULL policy name decoded by xdr_nullstring(), which allows remote authenticated users to cause a denial of service (kadmind crash via NULL pointer dereference) by sending a policy request with an empty policy name that reaches authorization checks or logging code.
krb5_ktkdb_get_entry() in lib/kdb/keytab.c in MIT Kerberos 5 (aka krb5) 1.2.8 and later does not free decrypted key material when a post-decryption check fails, which allows remote attackers to cause a denial of service (memory leak in the KDC or kadmind) via requests that repeatedly trigger key decryption failures.
xdr_krb5_tl_data() in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) does not free partially decoded data on failure, which allows remote authenticated users to cause a denial of service (memory leak in kadmind) via crafted RPC requests that trigger a decode failure.
The RPCSEC_GSS authentication routines in lib/rpc/authgss_prot.c in MIT Kerberos 5 (aka krb5) 1.4 and later do not free partially decoded buffers on failure, which allows remote attackers to cause a denial of service (memory leak in kadmind) via crafted RPCSEC_GSS messages.
clnttcp_call() in lib/rpc/clnt_tcp.c in MIT Kerberos 5 (aka krb5) does not free the RPC reply verifier between retries, which allows remote attackers to cause a denial of service (memory leak in GSS-RPC client programs) by injecting RPC replies with mismatched XIDs or by triggering authentication retries.
krb5: Improper authorization via flawed PAC checksum verification
krb5: Unauthorized key reset of protected principal via kpasswd
A path traversal attack in simulation of actions in the Zypp backend of PackageKit before 1.4.1 could be used by local attackers to gain root privileges.
gstreamer1-plugins-bad-free: gstreamer1-plugins-bad-free: Out-of-bounds read in mxfdemux via unchecked delta_id and slice index
gstreamer1-plugins-bad-free: gst-plugins-bad: use of uninitialized GstH265HRDParams in gst_h265_parse_vps() multi-HRD workaround loop
gst-plugins-good: gst-plugins-good: Local file disclosure via unvalidated file:// URIs in adaptivedemux2 manifest handling
A flaw was found in GStreamer's gst-plugins-good, specifically in the H.264 RTP depayloader element. When processing MTAP16 or MTAP24 multi-time aggregation RTP packets, a signed/unsigned integer conversion error causes the remaining-length counter to underflow to a large positive value when the packet is truncated. This allows a remote, unauthenticated attacker to trigger an out-of-bounds heap read of up to approximately 64 KiB of process memory by sending a single…
