CVE-2021-3467 2 Fedoraproject, Jasper Project 2 Fedora, Jasper 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A NULL pointer dereference flaw was found in the way Jasper versions before 2.0.26 handled component references in CDEF box in the JP2 image format decoder. A specially crafted JP2 image file could cause an application using the Jasper library to crash when opened.
CVE-2021-3463 1 Lenovo 125 Power Management Driver, Thinkpad 11e Gen 5, Thinkpad 11e Yoga Gen 6 and 122 more 2024-11-21 4.9 MEDIUM 4.2 MEDIUM
A null pointer dereference vulnerability in Lenovo Power Management Driver for Windows 10, prior to version 1.67.17.54, that could cause systems to experience a blue screen error.
CVE-2021-3449 12 Checkpoint, Debian, Fedoraproject and 9 more 167 Multi-domain Management, Multi-domain Management Firmware, Quantum Security Gateway and 164 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).
CVE-2021-3443 3 Fedoraproject, Jasper Project, Redhat 3 Fedora, Jasper, Enterprise Linux 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A NULL pointer dereference flaw was found in the way Jasper versions before 2.0.27 handled component references in the JP2 image format decoder. A specially crafted JP2 image file could cause an application using the Jasper library to crash when opened.

CVE-2021-3236 1 Vim 1 Vim 2024-11-21 N/A 5.5 MEDIUM
vim 8.2.2348 is affected by null pointer dereference, allows local attackers to cause a denial of service (DoS) via the ex_buffer_all method.
CVE-2021-3119 1 Zetetic 1 Sqlcipher 2024-11-21 5.0 MEDIUM 7.5 HIGH
Zetetic SQLCipher 4.x before 4.4.3 has a NULL pointer dereferencing issue related to sqlcipher_export in crypto.c and sqlite3StrICmp in sqlite3.c. This may allow an attacker to perform a remote denial of service attack. For example, an SQL injection can be used to execute the crafted SQL command sequence, which causes a segmentation fault.
