kernel: udp: Set SOCK_RCU_FREE earlier in udp_lib_get_port()

In the Linux kernel, the following vulnerability has been resolved: udp: Set SOCKRCUFREE earlier in udplibgetport. syzkaller triggered the warning 0 in udpv4earlydemux. In udpv46earlydemux and sklookup, we do not touch the refcount of the looked-up sk and use sockpfree as skb-destructor, so we...

eap-7: heap exhaustion via deserialization

A flaw was found in EAP-7 during deserialization of certain classes, which permits instantiation of HashMap and HashTable with no checks on resources consumed. This issue could allow an attacker to submit malicious requests using these classes, which could eventually exhaust the heap and result i...

CVE-2024-47188

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, missing initialization of the random seed for "thash" leads to byte-range tracking having predictable hash table behavior. This can lead to an attacker...

CVE-2024-47188 Suricata http/byte-ranges: missing hashtable random seed leads to potential DoS

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, missing initialization of the random seed for "thash" leads to byte-range tracking having predictable hash table behavior. This can lead to an attacker...

CVE-2024-47188

Suricata (IDS/IPS/NSM engine) is affected by CVE-2024-47188 and related 7.x/8.x issues. PTSecurity entries describe heap overflow in logging verdict information (eve.alert/eve.drop) for Suricata versions prior to 7.0.13 and prior to 8.0.2, potentially crashing the process. A workaround mentioned ...

Amazon Linux 2 : xerces-j2 (ALAS-2024-2649)

The version of xerces-j2 installed on the remote host is prior to 2.11.0-17. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2649 advisory. Apache Xerces2 Java Parser before 2.12.0 allows remote attackers to cause a denial of service CPU consumption via a crafted...

Medium: xerces-j2

Issue Overview: Apache Xerces2 Java Parser before 2.12.0 allows remote attackers to cause a denial of service CPU consumption via a crafted message to an XML service, which triggers hash table collisions. CVE-2012-0881 There's a vulnerability within the Apache Xerces Java XercesJ XML parser when...

kernel: xdp: Remove WARN() from __xdp_reg_mem_model()

A flaw was found in the Linux kernel's xdp subsystem in the xdpregmemmodel function where a memory allocation failure will trigger a warning if the function memidinithashtable returns an error. This warning is unnecessary as it elevates the severity of a memory allocation failure and pollutes the...
