K97324400: OpenSSL vulnerability CVE-2019-1563

Security Advisory Description In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypt...

K08044291: OpenSSL vulnerability CVE-2018-0739

Security Advisory Description Constructed ASN.1 types with a recursive definition such as can be found in PKCS7 could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that...

USN-5872-1 nss vulnerabilities

Tavis Ormandy discovered that NSS incorrectly handled an empty pkcs7 sequence. A remote attacker could possibly use this issue to cause NSS to crash, resulting in a denial of service. CVE-2022-22747 Ronald Crane discovered that NSS incorrectly handled certain memory operations. A remote attacker...

SUSE CVE-2022-2509

A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutlspkcs7verify function...

SUSE CVE-2022-22747

After accepting an untrusted certificate, handling an empty pkcs7 sequence as part of the certificate data could have lead to a crash. This crash is believed to be unexploitable. This vulnerability affects Firefox ESR 91.5, Firefox 96, and Thunderbird 91.5...

K000132537: OpenSSL vulnerabilities CVE-2022-4203, CVE-2023-0216, CVE-2023-0217, and CVE-2023-0401

Security Advisory Description CVE-2022-4203 A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or...

NULL Pointer Dereference

openssl is vulnerable to NULL Pointer Dereference. The vulnerability exists because it can be triggered when an application tries to load malformed PKCS7 data which can lead to an application crash...

Denial Of Service (DoS)

openssl is vulnerable to Denial Of Service DoS. The vulnerability exists because if a recipe cms recipient public key is invalid, the new filter bio is freed and the function returns a NULL result indicating a failure The public API function BIOnewNDEF is a helper function used for streaming ASN....

PT-2023-33053 · Openssl · Openssl

Name of the Vulnerable Software and Affected Versions: OpenSSL versions prior to 1.1.0 Description: A null pointer in OpenSSL can be dereferenced when signatures are being verified in malformed PKCS7 data, potentially causing unexpected crashes in agents or clients compiled with OpenSSL...

openssl-src vulnerable to Use-after-free following `BIO_new_NDEF`

The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. The function receives a BIO from the...

GHSA-R7JW-WP68-3XCH openssl-src vulnerable to Use-after-free following `BIO_new_NDEF`

The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. The function receives a BIO from the...

GHSA-VRH7-X64V-7VXQ openssl-src contains `NULL` dereference during PKCS7 data verification

A NULL pointer can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail...

AZL-13301 CVE-2023-0215 affecting package cloud-hypervisor for versions less than 30.0-2

The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications. The function receives a BIO from the...

ALPINE-CVE-2023-0216

An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2iPKCS7, d2iPKCS7bio or d2iPKCS7fp functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in...
