Internet Bug Bounty: UAF in OpenSSL up to 3.0.7

A use-after-free vulnerability was found in OpenSSL up to version 3.0.7 following BIOnewNDEF calls. This could result in a crash when the BIOpop function is called after BIOnewNDEF fails and improperly cleans up the BIO chain. The vulnerability impacts the public API functions...

Security Bulletin: AIX is affected by a denial of service (CVE-2022-45061) due to Python

Summary A vulnerability in Python could allow a remote attacker to cause a denial of service CVE-2022-45061. Python is used by AIX as part of Ansible node management automation. Vulnerability Details CVEID:CVE-2022-45061 DESCRIPTION: Python is vulnerable to a denial of service, caused by an...

openssl: double free after calling PEM_read_bio_ex

A double-free vulnerability was found in OpenSSL's PEMreadbioex function. The function PEMreadbioex reads a PEM file from a BIO and parses and decodes the "name" for example, "CERTIFICATE", any header data, and the payload data. If the function succeeds, then the "nameout," "header," and "data"...

openssl: timing attack in RSA Decryption implementation

A timing-based side channel exists in the OpenSSL RSA Decryption implementation, which could be sufficient to recover a ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, an attacker would have to be able to send a very large number of trial messages...

openssl: read buffer overflow in X.509 certificate verification

A flaw was found in Open SSL. 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 for the...

openssl: use-after-free following BIO_new_NDEF

A use-after-free vulnerability was found in OpenSSL's BIOnewNDEF function. The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally by OpenSSL to support the SMIME, CMS, and PKCS7 streaming capabilities, but it may also be...

openssl: NULL dereference validating DSA public key

A flaw was found in OpenSSL. An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the EVPPKEYpubliccheck function, most likely leading to an application crash. This function can be called on public keys supplied from untrusted...

openssl: invalid pointer dereference in d2i_PKCS7 functions

A flaw was found in OpenSSL. 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. This may result in an application crash which could lead to a denial of service. The TLS implementati...

openssl: X.400 address type confusion in X.509 GeneralName

A type confusion vulnerability was found in OpenSSL when OpenSSL X.400 addresses processing inside an X.509 GeneralName. When CRL checking is enabled for example, the application sets the X509VFLAGCRLCHECK flag, this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call,...
