Read Time:15 Second

USN-5488-1 fixed vulnerabilities in OpenSSL. This update provides the
corresponding updates for Ubuntu 16.04 ESM.

Original advisory details:

Chancen and Daniel Fiala discovered that OpenSSL incorrectly handled the
c_rehash script. A local attacker could possibly use this issue to execute
arbitrary commands when c_rehash is run.

CVE-2021-3695

Read Time:29 Second

A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12.

Release Notes for 2.11.1

This is a SECURITY release. All users are encouraged to upgrade immediately.

Added

This release adds features to allow filtering a ServerRequest as generated by LaminasDiactorosServerRequestFactory::fromGlobals() for the purposes of initialization. Examples include:

Adding a request identifier.
Using X-Forwarded-* headers to modify the URL to represent the original client request.

The features are based on a new interface, LaminasDiactororsServerRequestFilterFilterServerRequestInterface, which defines a single method:

public function __invoke(
PsrHttpMessageServerRequestInterface $request
): PsrHttpMessageServerRequestInterface

We provide two implementations, as follows:

LaminasDiactorosServerRequestFilterDoNotFilter will return the provided request verbatim.
LaminasDiactorosServerRequestFilterFilterUsingXForwardedHeaders has named constructors that allow you to define how and when X-Forwarded- headers are used to modify the URI instance associated with the request. These methods are:
* trustAny(): this method generates a filter instance that will trust all X-Forwarded-
headers from any source.
* trustReservedSubnets(array $trustedHeaders = ?): this method generates a filter instance that only modifies the URL if the IP address of the requesting server is from a reserved, private subnet (localhost; classes A, B, and C subnets; and IPv6 private and local-link subnets). By default, it will trust all X-Forwarded- headers from these sources, but you may specify a list to allow via the $trustedHeaders argument.
* trustProxies(array $proxyCIDRList, array $trustedHeaders = ?): this method will generate a filter instance that only modifies the URL if the requesting server matches an entry in the $proxyCIDRList. These entries may be IP addresses, or any IPv4 or IPv6 CIDR subnets. By default, it will trust all X-Forwarded-
headers from these sources, but you may specify a list to allow via the $trustedHeaders argument.

ServerRequestFactory::fromGlobals() now accepts a FilterServerRequestInterface instance as the optional argument $requestFilter. If none is provided, it uses one as produced by FilterUsingXForwardedHeaders::trustReservedSubnets().

Deprecated

The function LaminasDiactorosmarshalUriFromSapi() is deprecated, and no longer used internally.

Changed

LaminasDiactorosServerRequestFactory::fromGlobals() no longer consumes marshalUriFromSapi(), and instead inlines an alternate implementation. The new implementation does not consider X-Forwarded- headers by default when generating the associated URI instance. Internally, if no FilterServerRequestInterface implementation is provided, it defaults to using an instance returned by FilterUsingXForwardeHeaders::trustReservedSubnets(). If you previously relied on X-Forwarded- headers, you MAY need to update your code to use either the FilterUsingXForwardedHeaders::trustAny() or FilterUsingXForwardedHeaders::trustProxies() methods to generate a filter to use with ServerRequestFactory::fromGlobals().

Fixed
