Package : openssl
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 the stable distribution (bullseye), these problems have been fixed in
version 1.1.1n-0+deb11u5.

We recommend that you upgrade your openssl packages.

tracker page at:

Anton Romanov discovered that OpenSSL incorrectly handled AES-XTS cipher decryption on 64-bit ARM platforms. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS, Ubuntu 22.10, and Ubuntu 23.04.

CVE-2023-2650

Issue summary: Processing some specially crafted ASN.1 object identifiers or data containing them may be very slow. Impact summary: Applications that use OBJ_obj2txt() directly, or use any of the OpenSSL subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience notable to very long delays when processing those messages, which may lead to a Denial of Service. An OBJECT IDENTIFIER is composed of a series of numbers - sub-identifiers - most of which have no size limit. OBJ_obj2txt() may be used to translate an ASN.1 OBJECT IDENTIFIER given in DER encoding form (using the OpenSSL type ASN1_OBJECT) to its canonical numeric text form, which are the sub-identifiers of the OBJECT IDENTIFIER in decimal form, separated by periods. When one of the sub-identifiers in the OBJECT IDENTIFIER is very large (these are sizes that are seen as absurdly large, taking up tens or hundreds of KiBs), the translation to a decimal number in text may take a very long time. T...

CVE-2023-0466

The function X509_VERIFY_PARAM_add0_policy() is documented to implicitly enable the certificate policy check when doing certificate verification. However the implementation of the function does not enable the check which allows certificates with invalid or incorrect policies to pass the certificate verification. As suddenly enabling the policy check could break existing deployments it was decided to keep the existing behavior of the X509_VERIFY_PARAM_add0_policy() function. Instead the applications that require OpenSSL to perform certificate policy check need to use X509_VERIFY_PARAM_set1_policies() or explicitly enable the policy check by calling X509_VERIFY_PARAM_set_flags() with the X509_V_FLAG_POLICY_CHECK flag argument. Certificate policy checks are disabled by default in OpenSSL and are not commonly used by applications.

CVE-2023-0465

Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks. Invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent policy checking on the certificate altogether. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function.

CVE-2023-0464

A security vulnerability has been identified in all supported versions of OpenSSL related to the verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use of computational resources, leading to a denial-of-service (DoS) attack on affected systems. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function.
