CVE-2023-1732 1 Cloudflare 1 Circl 2026-06-17 N/A 5.3 MEDIUM
When sampling randomness for a shared secret, the implementation of Kyber and FrodoKEM, did not check whether crypto/rand.Read() returns an error. In rare deployment cases (error thrown by the Read() function), this could lead to a predictable shared secret. The tkn20 and blindrsa components did not check whether enough randomness was returned from the user provided randomness source. Typically the user provides crypto/rand.Reader, which in the vast majority of cases will always return the right number random bytes. In the cases where it does not, or the user provides a source that does not, the blinding for blindrsa is weak and integrity of the plaintext is not ensured in tkn20.
CVE-2023-1577 1 Lenovo 1 Drivers Management 2026-06-17 N/A 7.8 HIGH
A path hijacking vulnerability was reported in Lenovo Driver Manager prior to version 3.1.1307.1308 that could allow a local user to execute code with elevated privileges.
CVE-2023-1289 3 Fedoraproject, Imagemagick, Redhat 4 Extra Packages For Enterprise Linux, Fedora, Imagemagick and 1 more 2026-06-17 N/A 5.5 MEDIUM
A vulnerability was discovered in ImageMagick where a specially created SVG file loads itself and causes a segmentation fault. This flaw allows a remote attacker to pass a specially crafted SVG file that leads to a segmentation fault, generating many trash files in "/tmp," resulting in a denial of service. When ImageMagick crashes, it generates a lot of trash files. These trash files can be large if the SVG file contains many render actions. In a denial of service attack, if a remote attacker uploads an SVG file of size t, ImageMagick generates files of size 103*t. If an attacker uploads a 100M SVG, the server will generate about 10G.
