An issue was discovered in Wind River VxWorks 6.9 and 7

CVE-2023-38346 8.8 - High - September 22, 2023

An issue was discovered in Wind River VxWorks 6.9 and 7. The function ``tarExtract`` implements TAR file extraction and thereby also processes files within an archive that have relative or absolute file paths. A developer using the "tarExtract" function may expect that the function will strip leading slashes from absolute paths or stop processing when encountering relative paths that are outside of the extraction path, unless otherwise forced. This could lead to unexpected and undocumented behavior, which in general could result in a directory traversal, and associated unexpected behavior.

Out-of-bounds Read

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client

CVE-2021-3449 5.9 - Medium - March 25, 2021

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

NULL Pointer Dereference

The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain

CVE-2021-3450 7.4 - High - March 25, 2021

The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. If a "purpose" has been configured then there is a subsequent opportunity for checks that the certificate is a valid CA. All of the named "purpose" values implemented in libcrypto perform this check. Therefore, where a purpose is set the certificate chain will still be rejected even when the strict flag has been used. A purpose is set by default in libssl client and server certificate verification routines, but it can be overridden or removed by an application. In order to be affected, an application must explicitly set the X509_V_FLAG_X509_STRICT verification flag and either not set a purpose for the certificate verification or, in the case of TLS client or server applications, override the default purpose. OpenSSL versions 1.1.1h and newer are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1h-1.1.1j).
