    Package        : leptonlib     Version        : 1.76.0-1+deb10u2     CVE ID         : CVE-2022-38266

    This update fixes a denial of service vulnerability in leptonlib. It can be     made to crash with an arithmetic exception on specially crafted JPEG files.

    For Debian 10 buster, this problem has been fixed in version     1.76.0-1+deb10u2.

    We recommend that you upgrade your leptonlib packages.

    For the detailed security status of leptonlib please refer to     its security tracker page at:

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The AlmaLinux 9.2 host has packages installed that are affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1784817741 advisory.

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The AlmaLinux 9.6 host has packages installed that are affected by a vulnerability as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1784970773 advisory.

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
