|---|---|---|---|---|---|
| CVE-2018-16395 | 4 Canonical, Debian, Redhat and 1 more | 5 Ubuntu Linux, Debian Linux, Enterprise Linux and 2 more | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations. | |||||
| CVE-2018-16336 | 3 Canonical, Debian, Exiv2 | 3 Ubuntu Linux, Debian Linux, Exiv2 | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file, a different vulnerability than CVE-2018-10999. | |||||
| CVE-2018-16323 | 2 Canonical, Imagemagick | 2 Ubuntu Linux, Imagemagick | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| ReadXBMImage in coders/xbm.c in ImageMagick before 7.0.8-9 leaves data uninitialized when processing an XBM file that has a negative pixel value. If the affected code is used as a library loaded into a process that includes sensitive information, that information sometimes can be leaked via the image data. | |||||
| CVE-2018-16276 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
| An issue was discovered in yurex_read in drivers/usb/misc/yurex.c in the Linux kernel before 4.17.7. Local attackers could use user access read/writes with incorrect bounds checking in the yurex USB driver to crash the kernel or potentially escalate privileges. | |||||
| CVE-2018-16152 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data in the digestAlgorithm.parameters field during PKCS#1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation when only an RSA signature is used for IKEv2 authentication. This is a variant of CVE-2006-4790 and CVE-2014-1568. | |||||
| CVE-2018-16151 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data after the encoded algorithm OID during PKCS#1 v1.5 signature verification. Similar to the flaw in the same version of strongSwan regarding digestAlgorithm.parameters, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation when only an RSA signature is used for IKEv2 authentication. | |||||
