CVE-2026-88052

Tesseract is an open-source OCR engine. In versions 5.5.3 and earlier , the function UNICHARSET::load_via_fgets (in src/ccutil/unicharset.cpp) uses a declared unichar count as a loop bound and indexes into the unichars vector with an unchecked id. Because unichar_insert_backwards_compatible can l...

CVE-2026-88051 Tesseract: Heap out-of-bounds write in GenericVector<T>::read due to independent reserved/size_used_ fields

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, the callback form of GenericVector::read in src/ccutil/genericvector.h reads the independent int32 fields reserved and sizeused from a .traineddata model without a cap or an invariant check. reservereserved allocates the backin...

CVE-2026-88050

A flaw was found in Tesseract. It was discovered that the RecodedCharID::DeSerialize function accepts negative code values from a specially crafted .traineddata recoder component. This can lead to an out-of-bounds write when SetupDecoder attempts to index a zero-sized vector with a negative code....

CVE-2026-88015

A flaw was found in rclone. When rclone is configured with backend/local and links=true, it exposes symlink targets as .rclonelink objects. A remote attacker can send a crafted Range request with an unchecked positive Range start, leading to a deterministic slice-bounds panic. This issue results ...

Tesseract is an open source OCR engine. In version 5.5.3 and earlier, RecodedCharID::DeSerialize in src/ccutil/unicharcompress.h validates length but accepts negative code values from a crafted .traineddata recoder component. UnicharCompress::ComputeCodeRange in src/ccutil/unicharcompress.cpp can...

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...
