CVE-2019-15145

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions DjVuLibre version 3.5.27
Description The issue is related to a missing zero-bytes check, which can be exploited by crafting a corrupted JB2 image file. This can cause a denial-of-service attack, leading to an application crash via an out-of-bounds read in the get direct context function of JB2Dict::JB2Codec in libdjvu/JB2Image.h. The vulnerability can be exploited by a remote attacker to cause a denial-of-service.
Recommendations For DjVuLibre version 3.5.27, consider updating to a newer version that includes a fix for the missing zero-bytes check in libdjvu/GBitmap.h. As a temporary workaround, avoid using the get direct context function of JB2Dict::JB2Codec until a patch is available. Restrict access to corrupted JB2 image files to minimize the risk of exploitation.
