* Bug 66425: Avoid exceptions found via poi-fuzzDominik Stadler2024-07-161-0/+0
| | | | | | | | | | | Avoid a possible OutOfMemoryException with many child-records This avoids having too many children in EscherRecords, the limit of 100_000 is arbitrarily chosen and can be adjusted if needed Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=62924 and maybe others git-svn-id: https://svn.apache.org/repos/asf/poi/trunk@1919272 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | | Avoid a possible StackOverflowException This adds support of counting of the "nesting level" into the base EscherRecord and thus makes this existing limitation much more effective as it kicks in for more types of nested records.

| | | | | | | | | | | | | | We try to generally avoid overly large allocations in places where arrays are allocated. We add one more such check for pictures in HSLF. We might need to increase the used value of 10MB if users report larger files being used frequently.

* Add the ability to edit HSLFPictureData contentsMarius Volkhart2021-02-281-0/+0
| | | | | | | | | | | | Pictures can now be edited by calling HSLFPictureData#setData(byte[]). The byte[] should contain the image data as an image viewer might read it. To enable this functionality, a tighter coupling between the EscherBSERecords of the slideshow and the HSLFPictureData was required. This ensures that changes in image data size are accurately recorded in the records. In the course of coupling the records and the HSLFPictureData, various scenarios arose where a mapping of records to pictures was non-trivial. Accordingly, the HSLFSlideShowImpl#matchPicturesAndRecords(...) function was added to perform a more sophisticated matching pass. This function is heavily exercised by org.apache.poi.hslf.usermodel.TestBugs.testFile[5] and PPTX2PNG.render[2], as well as the new TestPictures#testSlideshowWithIncorrectOffsets().
