openssl: OpenSSL: Denial of Service due to excessive memory allocation in TLS 1.3 certificate compression

A flaw was found in OpenSSL. A remote attacker can exploit this vulnerability by sending a specially crafted CompressedCertificate message during the TLS 1.3 handshake. This can cause excessive per-connection memory allocations, leading to resource exhaustion and a Denial of Service DoS for...

openssl: OpenSSL: Data integrity bypass in `openssl dgst` command due to silent truncation

A flaw was found in openssl. When a user signs or verifies files larger than 16MB using the openssl dgst command with one-shot algorithms, the tool silently truncates the input to 16MB. This creates an integrity gap, allowing trailing data beyond the initial 16MB to be modified without detection...

openssl: OpenSSL: Denial of Service due to out-of-bounds write in BIO filter

A flaw was found in OpenSSL. This vulnerability involves an out-of-bounds write in the line-buffering BIO filter, which can lead to memory corruption. While exploitation is unlikely to be under direct attacker control, a successful attack could cause an application to crash, resulting in a Denial...

openssl: OpenSSL: Remote code execution or Denial of Service via oversized Initialization Vector in CMS parsing

A flaw was found in OpenSSL. A remote attacker can exploit a stack buffer overflow vulnerability by supplying a crafted Cryptographic Message Syntax CMS message with an oversized Initialization Vector IV when parsing AuthEnvelopedData structures that use Authenticated Encryption with Associated...

openssl: OpenSSL: Denial of Service via type confusion in PKCS#7 signature verification

A flaw was found in OpenSSL. This type confusion vulnerability allows a remote attacker to cause a denial of service DoS by providing specially crafted PKCS7 data to an application that performs signature verification. The vulnerability occurs because the application accesses an ASN1TYPE union...

openssl: OpenSSL: Denial of Service due to type confusion in PKCS#12 file processing

A flaw was found in OpenSSL. This type confusion vulnerability allows a remote attacker to cause a Denial of Service DoS by tricking a user or application into processing a maliciously crafted PKCS12 Personal Information Exchange Syntax Standard file. The vulnerability leads to an invalid or NULL...

openssl: OpenSSL: Information disclosure and data tampering via specific low-level OCB encryption/decryption calls

A flaw was found in OpenSSL. When applications directly call the low-level CRYPTOocb128encrypt or CRYPTOocb128decrypt functions with non-block-aligned lengths in a single call on hardware-accelerated builds, the trailing 1-15 bytes of a message may be exposed in cleartext. These exposed bytes are...

Important: Red Hat Security Advisory: openssl security update

A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from...

openssl: OpenSSL: Denial of Service via NULL pointer dereference in QUIC protocol handling

A flaw was found in openssl. A remote attacker could trigger a NULL pointer dereference by sending an unknown or unsupported cipher ID during the client hello callback in applications using the QUIC Quick UDP Internet Connections protocol. This vulnerability, occurring when the SSLCIPHERfind...

openssl: OpenSSL: Denial of Service via malformed TimeStamp Response

A flaw was found in OpenSSL. A type confusion vulnerability exists in the TimeStamp Response verification code, where an ASN1TYPE union member is accessed without proper type validation. A remote attacker can exploit this by providing a malformed TimeStamp Response to an application that verifies...
