Ubuntu Security Notice USN-5710-1^[6]: Authored by Ubuntu ^[7] | Site security.ubuntu.com ^[8]; Ubuntu Security Notice 5710-1 - It was discovered that OpenSSL incorrectly handled certain X.509 Email Addresses. If a certificate authority were tricked into signing a specially-crafted certificate, a remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. The default compiler options for affected releases reduce the vulnerability to a denial of service. It was discovered that OpenSSL incorrectly handled applications creating custom ciphers via the legacy EVP_CIPHER_meth_new function. This issue could cause certain applications that mishandled values to the function to possibly end up with a NULL cipher and messages in plaintext.; systems | linux ^[9], ubuntu ^[10]; advisories | CVE-2022-3358 ^[11]; SHA-256 | 7b62b4888702cab45aeeaeff8c5ec0500b30513d208729751998d56e5717a938; Download ^[12] | Favorite ^[13] | View ^[14]

Ubuntu Security Notice USN-5710-1
November 01, 2022
openssl vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.10
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in OpenSSL.
Software Description:
- openssl: Secure Socket Layer (SSL) cryptographic library and tools
Details:
It was discovered that OpenSSL incorrectly handled certain X.509 Email
Addresses. If a certificate authority were tricked into signing a
specially-crafted certificate, a remote attacker could possibly use this
issue to cause OpenSSL to crash, resulting in a denial of service. The
default compiler options for affected releases reduce the vulnerability to
a denial of service. (CVE-2022-3602, CVE-2022-3786)
It was discovered that OpenSSL incorrectly handled applications creating
custom ciphers via the legacy EVP_CIPHER_meth_new() function. This issue
could cause certain applications that mishandled values to the function to
possibly end up with a NULL cipher and messages in plaintext.
(CVE-2022-3358)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.10:
libssl3                         3.0.5-2ubuntu2
Ubuntu 22.04 LTS:
libssl3                         3.0.2-0ubuntu1.7
After a standard system update you need to reboot your computer to make all
the necessary changes.
