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: 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 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: 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...

Important: Red Hat Security Advisory: openssl security update

An update for openssl is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from t...

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...

openssl: OpenSSL: Arbitrary code execution or denial of service through crafted PKCS#12 file

A flaw was found in OpenSSL. When an application processes a maliciously crafted PKCS12 file, an attacker can exploit a stack buffer overflow or a NULL pointer dereference. This can lead to a denial of service DoS by crashing the application, and in some cases, may enable arbitrary code execution...
