Descriptions
In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data.
En PHP versiones 7.2.x por debajo de 7.2.34, versiones 7.3.x por debajo de 7.3.23 y versiones 7.4.x por debajo de 7.4.11, cuando el modo AES-CCM es usado con la función openssl_encrypt() con 12 bytes IV, solo los primeros 7 bytes del IV está actualmente usado. Esto puede conllevar a una disminución de seguridad y datos de cifrado incorrectos
It was discovered that PHP incorrectly handled certain encrypt ciphers. An attacker could possibly use this issue to decrease security or cause incorrect encryption data. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. It was discovered that PHP incorrectly handled certain HTTP cookies. An attacker could possibly use this issue to forge cookie which is supposed to be secure. Various other issues were also addressed.
