Summary
Red Hat Security Advisory: A Subscription Management tool for finding and reporting Red Hat product usage
Notes
Topic
A Subscription Management tool for finding and reporting Red Hat product usage
Details
Red Hat Discovery, also known as Discovery, is an inspection and reporting tool that finds,
identifies, and reports environment data, or facts, such as the number of physical and virtual
systems on a network, their operating systems, and relevant configuration data stored within
them. Discovery also identifies and reports more detailed facts for some versions of key
Red Hat packages and products that it finds in the network.

"text": "The identified out-of-memory vulnerability in libtiff, triggered by a crafted TIFF file passed to the TIFFRasterScanlineSize64() API, presents a moderate severity concern rather than a important one due to several factors. Primarily, the exploit requires the crafted input to be smaller than 379 KB, imposing a limitation on the potential impact and reducing the likelihood of successful exploitation in practical scenarios. Furthermore, the nature of the vulnerability is limited to denial-of-service attacks, which, although disruptive, do not inherently pose a direct risk of data compromise or system compromise. However, it\u0027s important to acknowledge that denial-of-service attacks can still have significant operational implications, particularly in environments reliant on continuous availability.\n\nWithin regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-787: Out-of-bounds Write vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low.\n\nThe platform enforces hardening guidelines to apply the most restrictive settings necessary for operational requirements. Baseline configurations and system controls ensure secure software settings, while least functionality reduces the attack surface by disabling unauthorized services and ports. The environment employs IPS/IDS and antimalware solutions to detect and prevent malicious code exploiting out-of-bounds write vulnerabilities, using mechanisms such as file integrity monitoring and patch management. Robust input validation and error handling ensure all user inputs are thoroughly validated, preventing instability, data exposure, or privilege escalation. Finally, the platform uses memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) to strengthen resilience against out-of-bounds write exploits.",

Rigorous development practices, including static analysis, input validation, and error handling, detect and mitigate memory vulnerabilities before deployment. Process isolation and memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) preserve memory integrity by confining faults to individual workloads and preventing unauthorized access. Malicious code protections and continuous system monitoring detect anomalous memory activity and exploitation attempts, reducing the likelihood and impact of out-of-bounds read and write vulnerabilities.",

The vulnerability affects the accuracy of DNS responses, but not the availability or confidentiality of systems. Additionally, DNSSEC-enabled deployments and restricted recursive access can significantly mitigate exploitation risks. Therefore, while the flaw can misdirect network traffic and compromise trust in name resolution, it does not directly compromise the underlying server or client systems, justifying an Important \u2014 but not Critical \u2014 severity rating.\n\nTechnical Analysis:\nThe issue arises because BIND fails to strictly validate unsolicited resource records accompanying legitimate DNS responses. This gap allows forged recursive resolvers to be cached as valid entries. Since the attack is remote, requires no authentication, and exploits a low-complexity vector, it is highly impactful in recursive resolver environments\u2014especially those exposed to untrusted clients or open resolvers.",

This weakness allows an attacker to potentially predict the source port and query ID used by BIND, enabling cache poisoning attacks. If successful, the attacker can inject malicious DNS responses into the resolver\u2019s cache, causing clients to receive spoofed DNS data. Authoritative servers are generally unaffected, but recursive resolvers are exposed to this risk. Exploitation is remote and does not require user interaction.",

"category": "other",
"text": "This vulnerability in BIND 9 resolvers caused by a weakness in the Pseudo Random Number Generator (PRNG) used to select the UDP source port and DNS query (transaction) ID. Exploitation requires an attacker to correctly predict both values and race the legitimate authoritative response with a spoofed packet to perform cache poisoning. While the PRNG weakness reduces entropy and makes prediction feasible under certain conditions, this still requires precise timing, on-path or spoofing capabilities, and targeting of recursive resolvers.\n\nThe impact is limited to resolver cache integrity; it does not allow remote code execution, privilege escalation, or direct compromise of the BIND server itself. Authoritative servers are not affected. Additionally, operational mitigations such as DNSSEC validation, access control restricting recursion, and network-level packet filtering reduce real-world exploitability. No active exploits have been observed in the wild.\n\nBecause exploitation is non-trivial, requires network-level spoofing and precise timing, and only affects cache integrity without server compromise, the vulnerability is considered Important rather than Critical.",
