Linux Distros Unpatched Vulnerability : CVE-2026-73066
medium Nessus Plugin ID 334657
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- Tesseract is an open source OCR engine. Prior to 5.5.3, a crafted .traineddata LSTM model component loaded through Tesseract's deserializer can cause an unchecked signed integer multiplication in Convolve::DeSerialize in src/lstm/convolve.cpp to wrap the convolution output-channel count, undersizing the forward-pass output buffer while writes use the unwrapped element count and causing a heap out-of- bounds write during OCR recognition. This issue is fixed in version 5.5.3. (CVE-2026-73066)
Note that Nessus relies on the presence of the package as reported by the vendor.
