Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2025-9230)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when trying to decrypt CMS messages encrypted using password based encryption. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.

Successful exploitation of the vulnerability requires that password based (PWRI) encryption support in CMS messages is enabled. 


2) Resource exhaustion (CVE-ID: CVE-2025-6176)

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 in its brotli decompression implementation. A remote attacker can trigger resource exhaustion and crash clients with less than 80GB of available memory.


3) Out-of-bounds read (CVE-ID: CVE-2025-66293)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the png_image_read_composite() function. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.


4) Out-of-bounds write (CVE-ID: CVE-2025-69419)

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

The vulnerability exists due to a boundary error within the PKCS12_get_friendlyname() function when parsing PKCS#12 file with a BMPString (UTF-16BE) friendly name containing non-ASCII BMP code point. A remote attacker can pass a specially crafted PKCS#12 file to the application, trigger an out-of-bounds write and perform a denial of service attack.
