Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) 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.
2) Cleartext transmission of sensitive information (CVE-ID: CVE-2025-69418)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to the trailing 1-15 bytes of a message may be exposed in cleartext on encryption and are not covered by the authentication tag. When using the low-level OCB API directly with AES-NI or other hardware-accelerated code paths, inputs whose length is not a multiple of 16 bytes can leave the final partial block unencrypted and unauthenticated. A remote attacker can intercept traffic and gain access to potentially sensitive information.
3) 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.
4) Type Confusion (CVE-ID: CVE-2025-69420)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a type confusion error within the TS_RESP_verify_response() function when handling ASN1_TYPE data.. A remote attacker can pass a malformed TimeStamp Response to the application and perform a denial of service attack.
5) NULL pointer dereference (CVE-ID: CVE-2025-69421)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the PKCS12_item_decrypt_d2i_ex function. A remote attacker can pass a specially crafted PKCS#12 file to the application and perform a denial of service (DoS) attack.
6) NULL pointer dereference (CVE-ID: CVE-2026-22795)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when parsing PKCS#12 file. A remote attacker can pass a specially crafted PKCS#12 file to the application and perform a denial of service (DoS) attack.
7) Type confusion (CVE-ID: CVE-2026-22796)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a type confusion error within the PKCS7_digest_from_attributes() function. A remote attacker can pass specially crafted PKCS#7 data to the application, trigger a type confusion error and perform a denial of service attack.
