| CVE-2020-36279 | Leptonica before 1.80.0 allows a heap-based buffer over-read in rasteropGeneralLow, related to adaptmap_reg.c and adaptmap.c. | [email protected] | 7.5 | 4.25% | 2021-03-12 | 2024-11-21 |
| CVE-2020-36278 | Leptonica before 1.80.0 allows a heap-based buffer over-read in findNextBorderPixel in ccbord.c. | [email protected] | 7.5 | 0.54% | 2021-03-12 | 2024-11-21 |
| CVE-2020-36277 | Leptonica before 1.80.0 allows a denial of service (application crash) via an incorrect left shift in pixConvert2To8 in pixconv.c. | [email protected] | 7.5 | 4.00% | 2021-03-11 | 2024-11-21 |
| CVE-2018-3836 | An exploitable command injection vulnerability exists in the gplotMakeOutput function of Leptonica 1.74.4. A specially crafted gplot rootname argument can cause a command injection resulting in arbitrary code execution. An attacker can provide a malicious path as input to an application that passes attacker data to this function to trigger this vulnerability. | [email protected] | 7.8 | 0.10% | 2018-04-24 | 2024-11-21 |
| CVE-2018-7442 | An issue was discovered in Leptonica through 1.75.3. The gplotMakeOutput function does not block '/' characters in the gplot rootname argument, potentially leading to path traversal and arbitrary file overwrite. | [email protected] | 9.1 | 0.19% | 2018-02-23 | 2024-11-21 |
| CVE-2018-7441 | Leptonica through 1.75.3 uses hardcoded /tmp pathnames, which might allow local users to overwrite arbitrary files or have unspecified other impact by creating files in advance or winning a race condition, as demonstrated by /tmp/junk_split_image.ps in prog/splitimage2pdf.c. | [email protected] | 7.0 | 0.04% | 2018-02-23 | 2024-11-21 |
| CVE-2018-7440 | An issue was discovered in Leptonica through 1.75.3. The gplotMakeOutput function allows command injection via a $(command) approach in the gplot rootname argument. This issue exists because of an incomplete fix for CVE-2018-3836. | [email protected] | 9.8 | 1.79% | 2018-02-23 | 2024-11-21 |
| CVE-2017-18196 | Leptonica 1.74.4 constructs unintended pathnames (containing duplicated path components) when operating on files in /tmp subdirectories, which might allow local users to bypass intended file restrictions by leveraging access to a directory located deeper within the /tmp directory tree, as demonstrated by /tmp/ANY/PATH/ANY/PATH/input.tif. | [email protected] | 3.3 | 0.04% | 2018-02-23 | 2024-11-21 |
| CVE-2018-7247 | An issue was discovered in pixHtmlViewer in prog/htmlviewer.c in Leptonica before 1.75.3. Unsanitized input (rootname) can overflow a buffer, leading potentially to arbitrary code execution or possibly unspecified other impact. | [email protected] | 9.8 | 0.39% | 2018-02-19 | 2024-11-21 |
| CVE-2018-7186 | Leptonica before 1.75.3 does not limit the number of characters in a %s format argument to fscanf or sscanf, which allows remote attackers to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a long string, as demonstrated by the gplotRead and ptaReadStream functions. | [email protected] | 9.8 | 3.12% | 2018-02-16 | 2024-11-21 |
