    Abstract: Provided is a method of dynamically applying a software patch to a computer program. A current version of a computer program is determined. Upon determination, compared to the current version, increasingly higher versions of the software patch are sequentially applied to the computer program, wherein the higher versions of the software patch are provided in form of a package.

    Abstract: Some examples described herein relate to dynamically applying a patch to a shared library. An external process may be invoked to bring target processes that refer to a shared library, to a safe point. In response to a function call from a target process, amongst the target processes, to access a target function in the shared library, the function call may be forwarded to a special function in a dynamic loader, wherein the target function is a function to be patched in the shared library. The special function may determine whether a shared patch library, comprising a patched version of the target function or a new function, is loaded for the target process. In response to determination that the shared patch library is not loaded for the target process, the shared patch library may be loaded only for the target process, and the request for the target function may be routed to the patched version of the target function or the new function, in the shared patch library.
