Description

This security bulletin contains information about 2 vulnerabilities.


1) Use-after-free (CVE-ID: CVE-2025-30232)

CWE-ID: CWE-416 - Use After Free

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


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the handling of the dp command line parameter. A local user with command-line access can trigger a use-after-free error and execute arbitrary code with elevated privileges.


2) SQL injection (CVE-ID: CVE-2025-26794)

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

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


The vulnerability allows a remote attacker to execute arbitrary SQL queries in application's database.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can send a specially crafted email to the affected server and execute arbitrary SQL commands within the application's database.

Note, the vulnerability exists only when the build time option _USE_SQLITE_ was set (it enables the use of SQLite for the hints databases), runtime config enables ETRN and enforces ETRN serialization.
