Description

This security bulletin contains information about 5 vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2025-4373)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/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 integer overflow within the g_string_insert_unichar() function in glib/gstring.c. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Improper input validation (CVE-ID: CVE-2025-27587)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote authenticated user to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Configuration (OpenSSL) component in Oracle Communications Cloud Native Core Certificate Management. A remote authenticated user can exploit this vulnerability to gain access to sensitive information.


3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2025-8916)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

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


The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to improper resource allocation. A remote attacker can library to consume excessive resources and perform a denial of service attack. 


4) Use-after-free (CVE-ID: CVE-2025-7425)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/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 within the xsltSetSourceNodeFlags() function. A remote attacker can pass specially crafted XML input to the application, trigger memory corruption and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


5) Buffer overflow (CVE-ID: CVE-2025-6965)

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:L/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 when processing aggregated terms. A remote attacker can pass specially crafted input to the application where the number of aggregate terms exceeds the number of columns available, trigger memory corruption and perform a denial of service (DoS) attack.
