Description

This security bulletin contains information about 5 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2017-13738)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

There is an illegal address access in the _lou_getALine function in compileTranslationTable.c:346 in Liblouis 3.2.0.


2) Buffer overflow (CVE-ID: CVE-2017-13739)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

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.


3) Buffer overflow (CVE-ID: CVE-2017-13740)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

There is a stack-based buffer overflow in Liblouis 3.2.0, triggered in the function parseChars() in compileTranslationTable.c, that will lead to denial of service or possibly unspecified other impact.


4) Buffer overflow (CVE-ID: CVE-2017-13742)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

There is a stack-based buffer overflow in Liblouis 3.2.0, triggered in the function includeFile() in compileTranslationTable.c, that will lead to a remote denial of service attack.


5) Out-of-bounds read (CVE-ID: CVE-2017-13744)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

There is an illegal address access in the function _lou_getALine() in compileTranslationTable.c:343 in Liblouis 3.2.0.
