CVE-2026-73066

A flaw was found in Tesseract, an open-source Optical Character Recognition OCR engine. A remote attacker could exploit this by providing a specially crafted .traineddata LSTM model component. When Tesseract's deserializer processes this component during OCR recognition, an unchecked integer...

CVE-2026-50538 libvncclient Tight decoder has an attacker-controlled heap out-of-bounds write

LibVNCClient is a library for easy implementation of a VNC client. In versions 0.9.12 through 0.9.15, a malicious or man-in-the-middle VNC server can force a connecting libvncclient to write attacker-controlled data past the end of its framebuffer. This is an out-of-bounds heap write with...

gstreamer1-plugins-good: gstreamer: unsigned integer underflow in avidemux FUJIFILM strd parsing leading to out-of-bounds read/write

A flaw was found in GStreamer gst-plugins-good avidemux. When parsing FUJIFILM metadata in an AVI strd chunk, gstavidemuxparsestrd decrements a remaining-length counter by fixed offsets 98 and 10 bytes without verifying sufficient data remains. For crafted strd payloads of exactly 106 or 107 byte...

CVE-2026-62357

Dragonfly's CMS.INITBYDIM and CMS.INITBYPROB commands in src/core/cms.cc accept dimensions whose width × depth × sizeof(int64_t) overflows, allocating an undersized counter buffer. An unauthenticated remote client can then use CMS.INCRBY/CMS.QUERY with unbounded dimensions to corrupt or disclose ...
