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

  - It was found that curl and libcurl might send their
    Authentication header to a third party HTTP server upon
    receiving an HTTP REDIRECT reply. This could leak
    authentication token to external
    entities.(CVE-2018-1000007)

  - When doing a TFTP transfer and curl/libcurl is given a
    URL that contains a very long file name (longer than
    about 515 bytes), the file name is truncated to fit
    within the buffer boundaries, but the buffer size is
    still wrongly updated to use the untruncated length.
    This too large value is then used in the sendto() call,
    making curl attempt to send more data than what is
    actually put into the buffer. The endto() function will
    then read beyond the end of the heap based buffer. A
    malicious HTTP(S) server could redirect a vulnerable
    libcurl-using client to a crafted TFTP URL (if the
    client hasn't restricted which protocols it allows
    redirects to) and trick it to send private memory
    contents to a remote server over UDP. Limit curl's
    redirect protocols with --proto-redir and libcurl's
    with CURLOPT_REDIR_PROTOCOLS.(CVE-2017-1000100)

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.");

"From Red Hat Security Advisory 2018:3157 :

An update for curl and nss-pem is now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The curl packages provide the libcurl library and the curl utility for
downloading files from servers using various protocols, including
HTTP, FTP, and LDAP.

The nss-pem package provides the PEM file reader for Network Security
Services (NSS) implemented as a PKCS#11 module.

Security Fix(es) :

* curl: HTTP authentication leak in redirects (CVE-2018-1000007)

* curl: FTP path trickery leads to NIL byte out of bounds write
(CVE-2018-1000120)

* curl: RTSP RTP buffer over-read (CVE-2018-1000122)

* curl: Out-of-bounds heap read when missing RTSP headers allows
information leak of denial of service (CVE-2018-1000301)

* curl: LDAP NULL pointer dereference (CVE-2018-1000121)

For more details about the security issue(s), including the impact, a
CVSS score, and other related information, refer to the CVE page(s)
listed in the References section.

Red Hat would like to thank the Curl project for reporting these
issues. Upstream acknowledges Craig de Stigter as the original
reporter of CVE-2018-1000007; Duy Phan Thanh as the original reporter
of CVE-2018-1000120; Max Dymond as the original reporter of
CVE-2018-1000122; the OSS-fuzz project as the original reporter of
CVE-2018-1000301; and Dario Weisser as the original reporter of
CVE-2018-1000121.
