There exists an out of bounds read/write in LibJXL versions prior to commit 9cc451b91b74ba470fd72bd48c121e9f33d24c99. The JPEG decoder used by the JPEG XL encoder when doing JPEG recompression (i.e. if using JxlEncoderAddJPEGFrame on untrusted input)...

There exists a stack buffer overflow in libjxl. A specifically-crafted file can cause the JPEG XL decoder to use large amounts of stack space (up to 256mb is possible, maybe 512mb), potentially exhausting the stack. An attacker can craft a file that ...

An issue was discovered in dec_patch_dictionary.cc in libjxl before 0.8.2. An integer underflow in patch decoding can lead to a denial of service, such as an infinite loop.

An out of bounds read exists in libjxl. An attacker using a specifically crafted file could cause an out of bounds read in the exif handler. We recommend upgrading to version 0.8.1 or past commit  https://github.com/libjxl/libjxl/pull/2101/commits/d9...

libjxl 0.6.1 has an assertion failure in LowMemoryRenderPipeline::Init() in render_pipeline/low_memory_render_pipeline.cc.

libjxl b02d6b9, as used in libvips 8.11 through 8.11.2 and other products, has an out-of-bounds write in jxl::ModularFrameDecoder::DecodeGroup (called from jxl::FrameDecoder::ProcessACGroup and jxl::ThreadPool::RunCallState<jxl::FrameDecoder::Process...

Invalid JPEG XL images using libjxl can cause an out of bounds access on a std::vector<std::vector<T>> when rendering splines. The OOB read access can either lead to a segfault, or rendering splines based on other process memory. It is recommended to...

For certain valid JPEG XL images with a size slightly larger than an integer number of groups (256x256 pixels) when processing the groups out of order the decoder can perform an out of bounds copy of image pixels from an image buffer in the heap to a...

libjxl v0.3.7 is affected by a Divide By Zero in issue in lib/extras/codec_apng.cc jxl::DecodeImageAPNG(). When encoding a malicous APNG file using cjxl, an attacker can trigger a denial of service.

libjxl v0.5.0 is affected by a Assertion failed issue in lib/jxl/image.cc jxl::PlaneBase::PlaneBase(). When encoding a malicous GIF file using cjxl, an attacker can trigger a denial of service.
