Summary
Intel® Manycore Platform Software Stack (Intel® MPSS) for Linux and Windows have addressed the following vulnerabilities in cURL/libcurl.
Vulnerability Details
CVEID: CVE-2016-9586
Description: cURL/libcurl is vulnerable to a buffer overflow, caused by improper boundary checks by the floating point conversion. By sending a specially crafted string, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 7.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119929> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2017-1000257
Description: cURL is vulnerable to a denial of service, caused by a buffer overread in the IMAP handler. By using a specially crafted IMAP FETCH response, a remote attacker could exploit this vulnerability to cause the application to crash or obtain sensitive information.
CVSS Base Score: 6.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/134033> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L)
CVEID: CVE-2017-8818
Description: cURL libcurl is vulnerable to a denial of service, caused by an out-of-bounds access flaw in the SSL library. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/135659> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-8816
Description: cURL libcurl is vulnerable to a buffer overflow, caused by an integer overflow flaw in the NTLM authentication feature. By using vectors involving long user and password fields, a remote attacker could overflow a buffer and execute arbitrary code and cause the application to crash.
CVSS Base Score: 9.8
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/135657> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2017-8817
Description: cURL libcurl could allow a remote attacker to bypass security restrictions, caused by an out-of-bounds read flaw in the FTP wildcard matching function (CURLOPT_WILDCARDMATCH). By using a string that ends with an ‘’[‘’ character, an attacker could exploit this vulnerability to redirect the victim to an arbitrary site.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/135658> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2017-7407
Description: curl could allow a physical attacker to obtain sensitive information, caused by an error in the ourWriteOut function in tool_writeout.c. By reading a workstation screen during use of a --write-out argument ending in a ‘’%‘’ character, an attacker could exploit this vulnerability to obtain sensitive information from process memory.
CVSS Base Score: 2.4
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/125384> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
