It was discovered that the AES-CBC implementation in the PHP Secure Communications Library was susceptible to a padding oracle timing attack. For the oldstable distribution (bookworm), these problems have been fixed in version 3.0.19-1+deb12u4. This update also fixes CVE-2023-52892. For the stable distribution (trixie), these problems have been fixed in. - ------------------------------------------------------------------------- Debian Security Advisory DSA-6187-1

Several security issues were fixed in OpenSSL.. =========================================================================Ubuntu Security Notice USN-4376-1 May 28, 2020 openssl vulnerabilities ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 19.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS Summary: Several security issues were fixed in OpenSSL. Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools Details: Cesar Pereida García, Sohaib ul Hassan, Nicola Tuveri, Iaroslav Gridin, Alejandro Cabrera Aldaya, and Billy Brumley discovered that OpenSSL incorrectly handled ECDSA signatures. An attacker could possibly use this issue to perform a timing side-channel attack and recover private ECDSA keys. (CVE-2019-1547) Matt Caswell discovered that OpenSSL incorrectly handled the random number generator (RNG). This may result in applications that use the fork() system call sharing the same RNG state between the parent and the child, contrary to expectations. This issue only affected Ubuntu 18.04 LTS and Ubuntu 19.10. (CVE-2019-1549) Guido Vranken discovered that OpenSSL incorrectly performed the x86_64 Montgomery squaring procedure. While unlikely, a remote attacker could possibly use this issue to recover private keys. (CVE-2019-1551) Bernd Edlinger discovered that OpenSSL incorrectly handled certain decryption functions. In certain scenarios, a remote attacker could possibly use this issue to perform a padding oracle attack and decrypt traffic. (CVE-2019-1563) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 19.10: libssl1.1 1.1.1c-1ubuntu4.1 Ubuntu 18.04 LTS: libssl1.1 1.1.1-1ubuntu2.1~18.04.6 Ubuntu 16.04 LTS: libssl1.0.0 1.0.2g-1ubuntu4.16 After a standard system update you needto reboot your computer to make all the necessary changes.
