openssl: OpenSSL: Arbitrary code execution due to out-of-bounds write in PKCS#12 processing

A flaw was found in OpenSSL. When processing a specially crafted PKCS12 Personal Information Exchange Syntax Standard file, a remote attacker can exploit an out-of-bounds write vulnerability. This issue, occurring within the OPENSSLuni2utf8 function, leads to memory corruption by writing data...

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: 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...

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: 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 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: 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.

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: Denial of Service via malformed PKCS#12 file processing

A flaw was found in OpenSSL. This vulnerability allows a remote attacker to trigger a Denial of Service DoS by providing a specially crafted, malformed PKCS12 file to an application that processes it. The flaw occurs due to a NULL pointer dereference in the PKCS12itemdecryptd2iex function when...

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...
