This Critical Patch Update contains 327 new security patches across the product families listed below. Oracle therefore strongly recommends that customers remain on actively-supported versions and apply Critical Patch Update security patches without delay. In some instances, it has been reported that attackers have been successful because targeted customers had failed to apply available Oracle patches. Oracle continues to periodically receive reports of attempts to maliciously exploit vulnerabilities for which Oracle has already released security patches. Refer to “Critical Patch Updates, Security Alerts and Bulletins” for information about Oracle Security advisories. Thus, prior Critical Patch Update advisories should be reviewed for information regarding earlier published security patches. These patches are usually cumulative, but each advisory describes only the security patches added since the previous Critical Patch Update Advisory. These patches address vulnerabilities in Oracle code and in third-party components included in Oracle products. The software is currently used as an offline tool for research purposes however, the software's embedded algorithms may also be useful for real-time treatment planning.Oracle Critical Patch Update Advisory - January 2023 DescriptionĪ Critical Patch Update is a collection of patches for multiple security vulnerabilities. We introduced and evaluated the clinical application of a highly automated software package, OCTOPUS, for quantitative plaque and stent analysis in IVOCT images. Regarding stent analysis, sensitivity and precision were both greater than 90%, and each strut was successfully classified as either covered or uncovered with high sensitivity (94%) and specificity (90%). Only up to 3.8% of plaque pixels were modified, leading to an average editing time of only 7.5 seconds/frame, an approximately 80% reduction compared to manual analysis. Using OCTOPUS on 34 new pullbacks, we determined that following automated segmentation, only 13% and 23% of frames needed any manual touch up for detailed lumen and calcification labeling, respectively. Underlying plaque segmentation algorithm yielded excellent pixel-wise results (86.2% sensitivity and 0.781 F1 score). Interactive visualizations include (x,y) anatomical, en face, and longitudinal views with optional overlays. Quantifications include stent deployment characteristics (e.g., stent strut malapposition), strut level analysis, calcium angle, and calcium thickness measurements. Interactive visualization and manual editing of segmentations were included in the software. To automate image analysis results, the software includes several important algorithmic steps: pre-processing, deep learning plaque segmentation, machine learning identification of stent struts, and registration of pullbacks. To aid IVOCT research studies, we developed the Optical Coherence TOmography PlaqUe and Stent (OCTOPUS) analysis software.
