CVE-2018-17294
CVSS v2.0
7.1
Alta
| Vetor | AV:N/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions:
Liblouis versions prior to 3.7
Description:
The issue is related to the
matchCurrentInput function inside lou translateString.c of Liblouis, which does not check the input string's length. This allows attackers to cause a denial of service by crafting an input file with certain translation dictionaries, leading to an application crash via out-of-bounds read.Recommendations:
For versions prior to 3.7, update to version 3.7 or later to resolve the issue.
As a temporary workaround, consider restricting the use of the
matchCurrentInput function until a patch is available.Exploit
