Vulnerabilities

Buffer Overflow vulnerability found in Liblouis v.3.24.0 allows a remote attacker to cause a denial of service via the compileTranslationTable.c and lou_setDataPath functions.

Liblouis 3.21.0 has an out-of-bounds write in compileRule in compileTranslationTable.c, as demonstrated by lou_trace.

Liblouis through 3.21.0 has a buffer overflow in compilePassOpcode in compileTranslationTable.c (called, indirectly, by tools/lou_checktable.c).

The matchCurrentInput function inside lou_translateString.c of Liblouis prior to 3.7 does not check the input string's length, allowing attackers to cause a denial of service (application crash via out-of-bounds read) by crafting an input file with certain translation dictionaries.

A missing patch for a stack-based buffer overflow in findTable() was found in Red Hat version of liblouis before 2.5.4. An attacker could cause a denial of service condition or potentially even arbitrary code execution.

Liblouis 3.6.0 has a stack-based Buffer Overflow in the function parseChars in compileTranslationTable.c, a different vulnerability than CVE-2018-11440.

Liblouis 3.5.0 has a stack-based Buffer Overflow in the function compileHyphenation in compileTranslationTable.c.

Liblouis 3.5.0 has a Segmentation fault in lou_logPrint in logging.c.

Liblouis 3.5.0 has a stack-based Buffer Overflow in the function parseChars in compileTranslationTable.c.

An issue was discovered in Liblouis 3.5.0. A invalid free in the compileRule function in compileTranslationTable.c allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

There is a heap-based buffer overflow that causes a more than two thousand bytes out-of-bounds write in Liblouis 3.2.0, triggered in the function resolveSubtable() in compileTranslationTable.c. It will lead to denial of service or remote code execution.
