The vulnerability of the NTLM type-2 function of the libcurl library, which allows a hacker to trigger a service failure

The vulnerability of NTLM type-2 in the libcurl library is related to incorrect validation of incoming data, which leads to reading beyond the buffer of dynamic memory. Exploiting this vulnerability allows a remote attacker to cause a service failure...

curl: Incorrect reuse of client certificates

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 leveragin...

curl: FTP path trickery leads to NIL byte out of bounds write

It was found that libcurl did not safely parse FTP URLs when using the CURLOPTFTPFILEMETHOD 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...

ALPINE-CVE-2016-8622

The URL percent-encoding decode function in libcurl before 7.51.0 is called curleasyunescape. Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get...

Haxx curl buffer overflow vulnerability

Haxx curl is a set of file transfer tools from the Swedish company Haxx that work on the command line using URL syntax, the tool supports file uploads and downloads, and includes a libcurl client-side URL transfer library for program development. A buffer overflow vulnerability exists in FTP URL...

ALPINE-CVE-2016-9952

The verifycertificate function in lib/vtls/schannel.c in libcurl 7.30.0 through 7.51.0, when built for Windows CE using the schannel TLS backend, makes it easier for remote attackers to conduct man-in-the-middle attacks via a crafted wildcard SAN in a server certificate, as demonstrated by ".com....

ALPINE-CVE-2016-9953

The verifycertificate function in lib/vtls/schannel.c in libcurl 7.30.0 through 7.51.0, when built for Windows CE using the schannel TLS backend, allows remote attackers to obtain sensitive information, cause a denial of service crash, or possibly have unspecified other impact via a wildcard...

UBUNTU-CVE-2018-1000007

libcurl 7.1 through 7.57.0 might accidentally leak authentication data to third parties. When asked to send custom headers in its HTTP requests, libcurl will send that set of headers first to the host in the initial URL but also, if asked to follow redirects and a 30X HTTP response code is...

UBUNTU-CVE-2017-8816

The NTLM authentication feature in curl and libcurl before 7.57.0 on 32-bit platforms allows attackers to cause a denial of service integer overflow and resultant buffer overflow, and application crash or possibly have unspecified other impact via vectors involving long user and password fields...

curl: IMAP FETCH response out of bounds read

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...

IMAP FETCH response out of bounds read

libcurl contains a buffer overrun flaw in the IMAP handler. An IMAP FETCH response line indicates the size of the returned data, in number of bytes. When that response says the data is zero bytes, libcurl would pass on that non-existing data with a pointer and the size zero to the deliver-data...

UBUNTU-CVE-2017-1000100

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...

TLS session resumption client cert bypass (again)

libcurl would attempt to resume a TLS session even if the client certificate had changed. That is unacceptable since a server by specification is allowed to skip the client certificate check on resume, and may instead use the old identity which was established by the previous certificate or no...

BSA-2017-216

Security Advisory ID : BSA-2017-216 Component : libcurl Revision : 1.0: Interim curl andlibcurlbefore 7.50.2, when built with NSS and the libnsspem.so library is available at runtime, allow remote attackers to hijack the authentication of a TLS connection by leveraging reuse of a previously loade...

CVE-2015-8625

MediaWiki before 1.23.12, 1.24.x before 1.24.5, 1.25.x before 1.25.4, and 1.26.x before 1.26.1 do not properly sanitize parameters when calling the cURL library, which allows remote attackers to read arbitrary files via an @ at sign character in unspecified POST array parameters...

cURL/libcURL TLS Certificate Validation Security Bypass Vulnerability

Haxx curl and libcurl are both products of the Swedish company Haxx. curl is a set of file transfer tools that utilize URL syntax to work at the command line. libcurl is a free, open source client-side URL transfer library. A security bypass vulnerability exists in cURL/libcURL. Allows an attacke...

uninitialized random

libcurl's new internal function that returns a good 32-bit random value was implemented poorly and overwrote the pointer instead of writing the value into the buffer the pointer pointed to. This random value is used to generate nonces for Digest and NTLM authentication, for generating boundary...
