TencentOS Server 4: suricata (TSSA-2024:1082)

high Nessus Plugin ID 239209

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:1082 advisory.

 Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

 CVE-2024-47522:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, invalid ALPN in TLS/QUIC traffic when JA4 matching/logging is enabled can lead to Suricata aborting with a panic. This issue has been addressed in 7.0.7. One may disable ja4 as a workaround.

 CVE-2024-45795:
 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 forcing lots of data into a single hash bucket, leading to severe performance degradation. This issue has been addressed in 7.0.7.

 CVE-2024-47187:
 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 datasets having predictable hash table behavior. This can lead to dataset file loading to use excessive time to load, as well as runtime performance issues during traffic handling. This issue has been addressed in 7.0.7. As a workaround, avoid loading datasets from untrusted sources. Avoid dataset rules that track traffic in rules.

 CVE-2024-47188:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, a logic error during fragment reassembly can lead to failed reassembly for valid traffic. An attacker could craft packets to trigger this behavior.This issue has been addressed in 7.0.7.

 CVE-2024-45796:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.7, rules using datasets with the non-functional / unimplemented unset option can trigger an assertion during traffic parsing, leading to denial of service. This issue is addressed in 7.0.7. As a workaround, use only trusted and well tested rulesets.

 CVE-2024-38534:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Crafted modbus traffic can lead to unlimited resource accumulation within a flow.
 Upgrade to 7.0.6. Set a limited stream.reassembly.depth to reduce the issue.

 CVE-2024-38536:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. A memory allocation failure due to `http.memcap` being reached leads to a NULL-ptr reference leading to a crash. Upgrade to 7.0.6.

 CVE-2024-38535:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Suricata can run out of memory when parsing crafted HTTP/2 traffic. Upgrade to 6.0.20 or 7.0.6.

 CVE-2024-24568:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.3, the rules inspecting HTTP2 headers can get bypassed by crafted traffic. The vulnerability has been patched in 7.0.3.

 CVE-2024-23839:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.3, specially crafted traffic can cause a heap use after free if the ruleset uses the http.request_header or http.response_header keyword. The vulnerability has been patched in 7.0.3. To work around the vulnerability, avoid the http.request_header and http.response_header keywords.

 CVE-2024-23835:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.3, excessive memory use during pgsql parsing could lead to OOM- related crashes. This vulnerability is patched in 7.0.3. As workaround, users can disable the pgsql app layer parser.

 CVE-2024-32664:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.5 and 6.0.19, specially crafted traffic or datasets can cause a limited buffer overflow. This vulnerability is fixed in 7.0.5 and 6.0.19. Workarounds include not use rules with `base64_decode` keyword with `bytes` option with value 1, 2 or 5 and for 7.0.x, setting `app- layer.protocols.smtp.mime.body-md5` to false.

 CVE-2024-23836:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 6.0.16 and 7.0.3, an attacker can craft traffic to cause Suricata to use far more CPU and memory for processing the traffic than needed, which can lead to extreme slow downs and denial of service. This vulnerability is patched in 6.0.16 or 7.0.3. Workarounds include disabling the affected protocol app-layer parser in the yaml and reducing the `stream.reassembly.depth` value helps reduce the severity of the issue.

 CVE-2024-37151:
 Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine.
 Mishandling of multiple fragmented packets using the same IP ID value can lead to packet reassembly failure, which can lead to policy bypass. Upgrade to 7.0.6 or 6.0.20. When using af-packet, enable `defrag` to reduce the scope of the problem.
