Description

This security bulletin contains information about 4 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2019-5273)

CWE-ID: CWE-119 - Memory corruption

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 a flaw in the X.509 implementation. A remote attacker can use a specially crafted certificate, trigger memory corruption and cause a denial of service condition on the target system.



2) Heap-based buffer overflow (CVE-ID: CVE-2019-5275)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

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 a boundary error in the X.509 implementation. A remote attacker can use a specially crafted certificate, trigger heap-based buffer overflow and cause a denial of service on the target system.



3) Infinite loop (CVE-ID: CVE-2019-5274)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

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 infinite loop in the X.509 implementation. A remote attacker can use a specially crafted certificate, consume all available system resources and cause a denial of service condition on the target system.


4) Improper validation of integrity check value (CVE-ID: CVE-2019-5272)

CWE-ID: CWE-354 - Improper Validation of Integrity Check Value

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to make malicious modifications.

The vulnerability exists due to the software of the affected products does not check the integrity. A remote authenticated attacker can make malicious modifications without detection.
