Successful exploitation of these vulnerabilities could lead to remote code execution or cause a denial-of-service condition, rendering the Sentinel LDK License Manager service unavailable.

No known public exploits specifically target these vulnerabilities. However, an attacker with low skill level could leverage the vulnerability.

In one vulnerability, language packs (zip files) with invalid HTML files lead to NULL pointer dereferences, which could be exploited by an attacker leveraging malicious HTML files. This could lead to a denial-of-service condition.

CVE-2017-11498 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.

In addition, language packs containing file names longer than 1,024 characters and malformed ASN.1 streams in input files can lead to a stack-based buffer overflow. This may allow remote code execution.

CVE-2017-11497 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.8.

Also, there is a malformed ASN.1 streams in V2C and similar input files can be used to generate stack-based buffer overflows. This could allow remote code execution.

CVE-2017-11496 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.8.

In addition, a XML payload with more than supported number of elements leads to buffer overflow of a variable in stack. This vulnerability can be exploited for denial of service.

CVE-2017-12818 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.

Also, a XML payload with more than supported number of elements leads to buffer overflow of a variable in stack. This vulnerability can be exploited for denial of service or arbitrary code execution.

CVE-2017-12821 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.8.

There is a malformed HTTP request body in Admin APIs can be used to generate heap buffer overflows. This vulnerability can be exploited for denial of service.

CVE-2017-12820 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.

In addition, a license manager web interface is enabled as a default configuration, and even if disabled, it can be re-enabled remotely. This vulnerability can be exploited to perform above mentioned attacks remotely.

CVE-2017-12822 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.9.

The product sees use in the communications, financial services, government facilities, healthcare and public health, and information technology sectors. It also sees action on a global basis.

Netherlands-based Gemalto recommends users who have Sentinel LDK run-time environment (RTE) Version 2.10 through Version 7.54 update to Sentinel LDK RTE component Version 7.6, or the latest version. The update was available as of July 2017.
