In `open_face` the initial stream is set on the face, along with the information about if FreeType is the owner of the stream object itself. The loaders may in the course of their work replace this stream with a new stream (as is the case for 'woff' and 'woff2'), which may have a different ownership than the initial stream object (likely the original stream object is owned by the user and is external, while the new stream object is created internally to FreeType and is internal). When the stream is replaced, the face's flags are updated with the new ownership status. However, `open_face` cannot itself free this stream as its caller `ft_open_face_internal` is responsible for this. In addition, in the case of an error `open_face` cannot return an actual face with the new stream and its ownership status to the caller. As a result, it must pass this information back to the caller as a sort of "failed face" so that the caller can clean up. `open_face` was already passing back the new stream but was not passing back the stream ownership information. As a result the stream may not have been free'd when needed. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=54700 * src/base/ftobjs.c (open_face): Pass back the ownership information as well. (ft_open_face_internal): Updated. |

FreeType 2.12.1 =============== Homepage: https://www.freetype.org FreeType is a freely available software library to render fonts. It is written in C, designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats. Please read the `docs/CHANGES` file, it contains IMPORTANT INFORMATION. Read the files `docs/INSTALL*` for installation instructions; see the file `docs/LICENSE.TXT` for the available licenses. For using FreeType's git repository instead of a distribution bundle, please read file `README.git`. Note that you have to actually clone the repository; using a snapshot will not work (in other words, don't use gitlab's 'Download' button). The FreeType 2 API reference is located in directory `docs/reference`; use the file `index.html` as the top entry point. [Please note that currently the search function for locally installed documentation doesn't work due to cross-site scripting issues.] Additional documentation is available as a separate package from our sites. Go to https://download.savannah.gnu.org/releases/freetype/ and download one of the following files. freetype-doc-2.12.1.tar.xz freetype-doc-2.12.1.tar.gz ftdoc2121.zip To view the documentation online, go to https://www.freetype.org/freetype2/docs/ Mailing Lists ------------- The preferred way of communication with the FreeType team is using e-mail lists. general use and discussion: freetype@nongnu.org engine internals, porting, etc.: freetype-devel@nongnu.org announcements: freetype-announce@nongnu.org git repository tracker: freetype-commit@nongnu.org The lists are moderated; see https://www.freetype.org/contact.html how to subscribe. Bugs ---- Please submit bug reports at https://gitlab.freedesktop.org/freetype/freetype/-/issues Alternatively, you might report bugs by e-mail to `freetype-devel@nongnu.org`. Don't forget to send a detailed explanation of the problem -- there is nothing worse than receiving a terse message that only says 'it doesn't work'. Patches ------- For larger changes please provide merge requests at https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests Alternatively, you can send patches to the `freetype-devel@nongnu.org` mailing list -- and thank you in advance for your work on improving FreeType! Details on the process can be found here: https://www.freetype.org/developer.html#patches Enjoy!
