New curl packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, 14.2, and -current to fix a security issue.

After testing original CVE-2016-5420 patch, it was discovered that libcurl built on top of NSS (Network Security Services) still incorrectly re-uses client certificates if a certificate from file is used for one TLS connection but no certificate is set for a subsequent TLS connection.

This update for curl fixes the following security issues :

  - CVE-2016-8624: invalid URL parsing with '#'     (bsc#1005646)

  - CVE-2016-8623: Use-after-free via shared cookies     (bsc#1005645)

  - CVE-2016-8622: URL unescape heap overflow via integer     truncation (bsc#1005643)

  - CVE-2016-8621: curl_getdate read out of bounds     (bsc#1005642)

  - CVE-2016-8620: glob parser write/read out of bounds     (bsc#1005640)

  - CVE-2016-8619: double-free in krb5 code (bsc#1005638)

  - CVE-2016-8618: double-free in curl_maprintf     (bsc#1005637)

  - CVE-2016-8617: OOB write via unchecked multiplication     (bsc#1005635)

  - CVE-2016-8616: case insensitive password comparison     (bsc#1005634)

  - CVE-2016-8615: cookie injection for other servers     (bsc#1005633)

  - CVE-2016-7167: escape and unescape integer overflows     (bsc#998760)

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.

- reject negative string lengths in curl_easy_[un]escape()     (CVE-2016-7167)

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

It was discovered that the four four libcurl functions curl_escape(), curl_easy_escape(), curl_unescape and curl_easy_unescape accepted negative sting length inputs.

For Debian 7 'Wheezy', these problems have been fixed in version 7.26.0-1+wheezy16.

We recommend that you upgrade your curl packages.
