Description
This security bulletin contains information about 8 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) Out-of-bounds write (CVE-ID: CVE-2025-68160)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary error within the BIO filter (BIO_f_linebuffer). A remote attacker can pass an overly long string to the application, trigger an out-of-bounds write and perform a denial of service attack.
3) 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.
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.
5) 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.
6) 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.
7) 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.
8) 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.
