EulerOS Virtualization 3.0.1.0 : curl (EulerOS-SA-2019-1549)

High Nessus Plugin ID 125002

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the curl packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- A NULL pointer dereference flaw was found in the way libcurl checks values returned by the openldap ldap_get_attribute_ber() function. A malicious LDAP server could use this flaw to crash a libcurl client application via a specially crafted LDAP reply.(CVE-2018-1000121)

- It was found that libcurl did not safely parse FTP URLs when using the CURLOPT_FTP_FILEMETHOD method. An attacker, able to provide a specially crafted FTP URL to an application using libcurl, could write a NULL byte at an arbitrary location, resulting in a crash, or an unspecified behavior.(CVE-2018-1000120)

- ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2016-8623)

- ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2016-8622)

- It was found that the libcurl library did not prevent TLS session resumption when the client certificate had changed. An attacker could potentially use this flaw to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.(CVE-2016-5419)

- A buffer overrun flaw was found in the IMAP handler of libcurl. By tricking an unsuspecting user into connecting to a malicious IMAP server, an attacker could exploit this flaw to potentially cause information disclosure or crash the application.(CVE-2017-1000257)

- ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2016-8624)

- ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2016-8621)

- A buffer over-read exists in curl 7.20.0 to and including curl 7.58.0 in the RTSP+RTP handling code that allows an attacker to cause a denial of service or information leakage(CVE-2018-1000122)

- ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2016-9586)

- The FTP wildcard function in curl and libcurl before 7.57.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) or possibly have unspecified other impact via a string that ends with an '' character.(CVE-2017-8817)

- ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2016-8618)

- It was found that the libcurl library using the NSS (Network Security Services) library as TLS/SSL backend incorrectly re-used client certificates for subsequent TLS connections in certain cases. An attacker could potentially use this flaw to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.(CVE-2016-7141)

- cURL and libcurl 7.10.6 through 7.34.0, when more than one authentication method is enabled, re-uses NTLM connections, which might allow context-dependent attackers to authenticate as other users via a request.(CVE-2014-0015)

- The tailMatch function in cookie.c in cURL and libcurl before 7.30.0 does not properly match the path domain when sending cookies, which allows remote attackers to steal cookies via a matching suffix in the domain of a URL.(CVE-2013-1944)

- It was discovered that the libcurl library failed to properly handle URLs with embedded end-of-line characters. An attacker able to make an application using libcurl access a specially crafted URL via an HTTP proxy could use this flaw to inject additional headers to the request or construct additional requests.(CVE-2014-8150)

- ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2016-8615)

- The default configuration in cURL and libcurl 7.10.6 before 7.36.0 re-uses (1) SCP, (2) SFTP, (3) POP3, (4) POP3S, (5) IMAP, (6) IMAPS, (7) SMTP, (8) SMTPS, (9) LDAP, and (10) LDAPS connections, which might allow context-dependent attackers to connect as other users via a request, a similar issue to CVE-2014-0015.(CVE-2014-0138)

- ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2016-8617)

- It was found that the libcurl library did not correctly handle partial literal IP addresses when parsing received HTTP cookies. An attacker able to trick a user into connecting to a malicious server could use this flaw to set the user's cookie to a crafted domain, making other cookie-related issues easier to exploit.(CVE-2014-3613)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected curl packages.
