CVE-2009-0846 [CRITICAL] CWE-824 CVE-2009-0846: The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime de The asn1_decode_generaltime function in lib/krb5/asn.1/asn1_decode.c in the ASN.1 GeneralizedTime decoder in MIT Kerberos 5 (aka krb5) before 1.6.4 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via vectors involving an invalid DER encoding that triggers a free of an uninitialized pointer.

CVE-2020-11501 [HIGH] CWE-330 CVE-2020-11501: GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3. GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol.

CVE-2012-3400 [HIGH] CWE-787 CVE-2012-3400: Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel before 3.4.5 allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem.

This issue A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution.

CVE-2014-3687 [HIGH] CWE-400 CVE-2014-3687: The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (panic) via duplicate ASCONF chunks that trigger an incorrect uncork within the side-effect interpreter.

CVE-2020-25645 [HIGH] CWE-319 CVE-2020-25645: A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoint A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidenti

CVE-2018-7054 [CRITICAL] CVE-2018-7054: An issue was discovered in Irssi before 1.0.7 and 1.1.x before 1.1.1. There is a use-after-free when An issue was discovered in Irssi before 1.0.7 and 1.1.x before 1.1.1. There is a use-after-free when a server is disconnected during netsplits.
