GLSA-202312-01 : Leptonica: Multiple Vulnerabilities

critical Nessus Plugin ID 187052

Language:

Description

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.

Solution

All Leptonica users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=media-libs/leptonica-1.81.0
