leptonica leptonica vulnerabilities and exploits

(subscribe to this query)

9.1

CVSSv3

An issue exists in Leptonica up to and including 1.75.3. The gplotMakeOutput function does not block '/' characters in the gplot rootname argument, potentially leading to path traversal and arbitrary file overwrite.

CVSSv3

Leptonica up to and including 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/splitimage...

9.8

CVSSv3

An issue exists in pixHtmlViewer in prog/htmlviewer.c in Leptonica prior to 1.75.3. Unsanitized input (rootname) can overflow a buffer, leading potentially to arbitrary code execution or possibly unspecified other impact.

3.3

CVSSv3

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...

Leptonica Leptonica 1.74.4

9.8

CVSSv3

An issue exists in Leptonica up to and including 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.

9.8

CVSSv3

Leptonica prior to 1.75.3 does not limit the number of characters in a %s format argument to fscanf or sscanf, which allows remote malicious users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a long string, as demonstrat...

7.8

CVSSv3

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 appl...

Leptonica Leptonica 1.74.4 Debian Debian Linux 7.0

7.5

CVSSv3

Leptonica prior to 1.80.0 allows a heap-based buffer over-read in pixReadFromTiffStream, related to tiffio.c.

6.5

CVSSv3

An issue in the Leptonica linked library (v1.79.0) allows malicious users to cause an arithmetic exception leading to a Denial of Service (DoS) via a crafted JPEG file.

Tesseract Project Tesseract 5.0.0 Leptonica Leptonica Debian Debian Linux 10.0

7.5

CVSSv3

Leptonica prior to 1.80.0 allows a denial of service (application crash) via an incorrect left shift in pixConvert2To8 in pixconv.c.
