Texas Instruments SimpleLink
An integer overflow exists in the APIs of the host MCU while trying to connect to a WIFI network may lead to issues such as a denial-of-service condition or code execution.CVE-2021-22677 has been assigned to this vulnerability. A CVSS v3 base score of 8.4 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The affected product is vulnerable to stack-based buffer overflow while processing over-the-air firmware updates from the CDN server, which may allow an attacker to remotely execute code.CVE-2021-22673 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H). The affected product is vulnerable to integer overflow while parsing malformed over-the-air firmware update files, which may allow an attacker to remotely execute code.CVE-2021-22675 has been assigned to this vulnerability. A CVSS v3 base score of 7.2 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H). The affected product is vulnerable to an integer overflow while processing HTTP headers, which may allow an attacker to remotely execute code.CVE-2021-22679 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Multiple integer overflow issues exist while processing long domain names, which may allow an attacker to remotely execute code.CVE-2021-22671 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
