CVE-2026-88052 Tesseract: Heap out-of-bounds write in UNICHARSET::load_via_fgets via count/insert desynchronization

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, UNICHARSET::loadviafgets in src/ccutil/unicharset.cpp trusts the declared unichar count as a loop bound and uses id as an unchecked index into the unichars vector. unicharinsertbackwardscompatible can leave the vector unchanged...

CVE-2026-88049

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, prior .traineddata hardening added bounds checks to NetworkIO::CopyTimeStepGeneral and NetworkIO::Randomize in src/lstm/networkio.cpp but left NetworkIO::WriteTimeStepPart and NetworkIO::AddTimeStepPart unchecked. In...

DEBIAN-CVE-2026-88048

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, FullyConnected::DeSerialize in src/lstm/fullyconnected.cpp does not validate the deserialized layer scalars ni and no against the weight-matrix dimensions. During FullyConnected::Forward, MatrixDotVector in...

CVE-2026-88048

A flaw was found in Tesseract. The FullyConnected::DeSerialize function does not properly validate the dimensions of deserialized layers against the weight-matrix dimensions. This vulnerability allows a remote attacker to provide a specially crafted .traineddata file, leading to a heap...

io.netty/netty-codec-http: Netty: Denial of Service via SPDY SETTINGS frame processing

A flaw was found in Netty, a network application framework. A remote attacker, by sending a specially crafted SPDY/3.1 SETTINGS frame, could cause the SPDY SETTINGS decoder to create a large number of map entries. This excessive processing and memory allocation can lead to a denial of service DoS...

com.fasterxml.jackson.core/jackson-core: tools.jackson.core/jackson-core: jackson-core: Denial of Service via incomplete fix in async JSON parser

A flaw was found in jackson-core. A remote attacker can exploit an incomplete fix in the non-blocking JSON parser by streaming specially crafted JSON data in small chunks. This bypasses the intended number length constraint, causing the parser to accumulate excessive memory per connection. This...
