Description
This security bulletin contains information about 10 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2024-11187)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when handling DNS zones with numerous records in the Additional section. A remote attacker can trigger resource exhaustion by sending multiple queries to he affected server and perform a denial of service (DoS) attack.
2) Stack-based buffer overflow (CVE-ID: CVE-2025-24928)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the xmlSnprintfElements() function in valid.c. A remote attacker can pass specially crafted XML data to the application, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Input validation error (CVE-ID: CVE-2025-27516)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to compromise the target system.
The vulnerability exists due to sandbox breakout through attr filter selecting format method. A local user can execute arbitrary code on the system.
4) Resource exhaustion (CVE-ID: CVE-2025-30204)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within the parse.ParseUnverified function when parsing authorization header. A remote attacker can send a specially crafted HTTP response to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Use-after-free (CVE-ID: CVE-2022-49043)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the xmlXIncludeAddNode() function in xinclude.c. A remote attacker can pass specially crafted XML input to the application, trigger a use-after-free error and crash the application or potentially execute arbitrary code.
6) Resource exhaustion (CVE-ID: CVE-2025-27144)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when parsing JWS and JWE input. A remote attacker can pass specially crafted data to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.
7) Information disclosure (CVE-ID: CVE-2025-29781)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to the Bare Metal Operator (BMO) can expose any secret from other namespaces via BMCEventSubscription CRD. A local user can gain unauthorized access to sensitive information on the system.
8) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2024-2236)
CWE-ID: CWE-208 - Information Exposure Through Timing Discrepancy
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform timing attack.
The vulnerability exists due to an error in libgcrypt's RSA implementation. A remote attacker can initiate a Bleichenbacher-style attack, which can lead to the decryption of RSA ciphertexts.
9) Out-of-bounds read (CVE-ID: CVE-2024-5535)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the SSL_select_next_proto() function when using NPN. A remote attacker can send specially crafted data to the application, trigger an out-of-bounds read and perform a denial of service (DoS) attack.
10) Use-after-free (CVE-ID: CVE-2024-55549)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in xsltGetInheritedNsList. A remote attacker can pass specially crafted input to the application, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
