[debian-lts-announce] 20181106 [SECURITY] [DLA 1568-1] curl security update

GLSA-201701-47

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)

  - 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)

Several vulnerabilities were discovered in cURL, an URL transfer library.

CVE-2016-7141

When built with NSS and the libnsspem.so library is available at runtime, allows an remote attacker to hijack the authentication of a TLS connection by leveraging reuse of a previously loaded client certificate from file for a connection for which no certificate has been set, a different vulnerability than CVE-2016-5420.

CVE-2016-7167

Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow.

CVE-2016-9586

Curl is vulnerable to a buffer overflow when doing a large floating point output in libcurl's implementation of the printf() functions. If there are any applications that accept a format string from the outside without necessary input filtering, it could allow remote attacks.

CVE-2018-16839

Curl is vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service.

CVE-2018-16842

Curl is vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 7.38.0-4+deb8u13.

We recommend that you upgrade your curl packages.

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

  - 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)

  - 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)

  - 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)

  - curl version curl 7.20.0 to and including curl 7.59.0     contains a Buffer Over-read vulnerability in denial of     service that can result in curl can be tricked into     reading data beyond the end of a heap based buffer used     to store downloaded rtsp content.(CVE-2018-1000301)

  - curl version curl 7.20.0 to and including curl 7.59.0     contains a Buffer Over-read vulnerability in denial of     service that can result in curl can be tricked into     reading data beyond the end of a heap based buffer used     to store downloaded rtsp content.(CVE-2016-9586)

  - libcurl may read outside of a heap allocated buffer     when doing FTP. When libcurl connects to an FTP server     and successfully logs in (anonymous or not), it asks     the server for the current directory with the `PWD`     command. The server then responds with a 257 response     containing the path, inside double quotes. The returned     path name is then kept by libcurl for subsequent uses.
    Due to a flaw in the string parser for this directory     name, a directory name passed like this but without a     closing double quote would lead to libcurl not adding a     trailing NUL byte to the buffer holding the name. When     libcurl would then later access the string, it could     read beyond the allocated heap buffer and crash or     wrongly access data beyond the buffer, thinking it was     part of the path. A malicious server could abuse this     fact and effectively prevent libcurl-based clients to     work with it - the PWD command is always issued on new     FTP connections and the mistake has a high chance of     causing a segfault. The simple fact that this has issue     remained undiscovered for this long could suggest that     malformed PWD responses are rare in benign servers. We     are not aware of any exploit of this flaw. This bug was     introduced in commit     [415d2e7cb7](https://github.com/curl/curl/commit/415d2e     7cb7), March 2005. In libcurl version 7.56.0, the     parser always zero terminates the string but also     rejects it if not terminated properly with a final     double quote.(CVE-2017-1000254)

  - 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.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)

This update for curl fixes the following issues :

Security issue fixed :

  - CVE-2016-9586: libcurl printf floating point buffer     overflow (bsc#1015332)

  - CVE-2017-7407: The ourWriteOut function in     tool_writeout.c in curl might have allowed physically     proximate attackers to obtain sensitive information from     process memory in opportunistic circumstances by reading     a workstation screen during use of a --write-out     argument ending in a '%' character, which lead to a     heap-based buffer over-read (bsc#1032309).

With this release new default ciphers are active (SUSE_DEFAULT, bsc#1027712).

libcurl's implementation of the printf() functions triggers a buffer overflow when doing a large floating point output. If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks. This flaw does not exist in the command line tool.

The remote host is affected by the vulnerability described in GLSA-201701-47 (cURL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in cURL. Please review the       CVE identifiers and bug reports referenced for details.
  Impact :

    Remote attackers could conduct a Man-in-the-Middle attack to obtain       sensitive information, cause a Denial of Service condition, or execute       arbitrary code.
  Workaround :

    There is no known workaround at this time.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that libcurl's implementation of the printf() functions triggers a buffer overflow when doing a large floating point output. The bug occurs when the conversion outputs more than 255 bytes.

The flaw happens because the floating point conversion is using system functions without the correct boundary checks.

If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks.

This flaw does not exist in the command line tool.

For Debian 7 'Wheezy', these problems have been fixed in version 7.26.0-1+wheezy18.

We recommend that you upgrade your curl packages.
