| CVE-2022-38266 | MEDIO6.5 | An issue in the Leptonica linked library (v1.79.0) allows attackers to cause an arithmetic exception leading to a Denial of Service (DoS) via a crafted JPEG file. | 09/09/2022 |
| CVE-2020-36281 | ALTO7.5 | Leptonica before 1.80.0 allows a heap-based buffer over-read in pixFewColorsOctcubeQuantMixed in colorquant1.c. | 12/03/2021 |
| CVE-2020-36280 | ALTO7.5 | Leptonica before 1.80.0 allows a heap-based buffer over-read in pixReadFromTiffStream, related to tiffio.c. | 12/03/2021 |
| CVE-2020-36279 | ALTO7.5 | Leptonica before 1.80.0 allows a heap-based buffer over-read in rasteropGeneralLow, related to adaptmap_reg.c and adaptmap.c. | 12/03/2021 |
| CVE-2020-36278 | ALTO7.5 | Leptonica before 1.80.0 allows a heap-based buffer over-read in findNextBorderPixel in ccbord.c. | 12/03/2021 |
| CVE-2020-36277 | ALTO7.5 | Leptonica before 1.80.0 allows a denial of service (application crash) via an incorrect left shift in pixConvert2To8 in pixconv.c. | 11/03/2021 |
| CVE-2018-3836 | ALTO7.8 | 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 thi | 24/04/2018 |
| CVE-2018-7442 | CRÍTICO9.1 | 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. | 23/02/2018 |
| CVE-2018-7441 | ALTO7.0 | 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. | 23/02/2018 |
| CVE-2018-7440 | CRÍTICO9.8 | 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. | 23/02/2018 |
| CVE-2017-18196 | BAJO3.3 | 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/ | 23/02/2018 |
| CVE-2018-7247 | CRÍTICO9.8 | 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. | 19/02/2018 |
| CVE-2018-7186 | CRÍTICO9.8 | 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. | 16/02/2018 |
