Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) 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.
2) Stack-based buffer overflow (CVE-ID: CVE-2025-15467)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing CMS AuthEnvelopedData structures that use AEAD ciphers such as AES-GCM, the IV (Initialization Vector) encoded in the ASN.1 parameters. A remote attacker can supply a specially crafted CMS message with an oversized IV, 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) 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-2025-9230)
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.
5) Integer overflow (CVE-ID: CVE-2025-13601)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to integer overflow within the g_escape_uri_string() function. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and perform a denial of service attack.
