- ------------------------------------------------------------------------- Debian LTS Advisory DLA-3449-1 [email protected] https://www.debian.org/lts/security/ Sylvain Beucler June 08, 2023 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------

Package : openssl Version : 1.1.1n-0+deb10u5 CVE ID : CVE-2023-0464 CVE-2023-0465 CVE-2023-0466 CVE-2023-2650 Debian Bug : 1034720

Multiple vulnerabilities have been discovered in OpenSSL, a Secure Sockets Layer toolkit.

CVE-2023-0464

David Benjamin reported a flaw related to the verification of X.509 certificate chains that include policy constraints, which may result in denial of service.

CVE-2023-0465

David Benjamin reported that invalid certificate policies in leaf certificates are silently ignored. A malicious CA could take advantage of this flaw to deliberately assert invalid certificate policies in order to circumvent policy checking on the certificate altogether.

CVE-2023-0466

David Benjamin discovered that the implementation of the X509_VERIFY_PARAM_add0_policy() function does not enable the check which allows certificates with invalid or incorrect policies to pass the certificate verification (contrary to its documentation).

CVE-2023-2650

It was discovered that processing malformed ASN.1 object identifiers or data may result in denial of service.

For Debian 10 buster, these problems have been fixed in version 1.1.1n-0+deb10u5.

We recommend that you upgrade your openssl packages.

For the detailed security status of openssl please refer to its security tracker page at:
