The remote host is affected by the vulnerability described in GLSA-202312-01 (Leptonica: Multiple Vulnerabilities)

  - 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. (CVE-2017-18196)

  - 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. (CVE-2018-7186)

  - 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. (CVE-2018-7247)

  - 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. (CVE-2018-7440)

  - 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. (CVE-2018-7441)

  - 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. (CVE-2018-7442)

  - 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. (CVE-2022-38266)
