Out Of Bound Reads (OOB)

libcurl.so is vulnerable to out of boundOOB reads. When an IMAP FETCH response showing the size of the returned data is zero, libcurl's deliver-data function calls the strlen function which can lead to out of bound reads on the heap and/or crashes the application...

Arbitrary Code Execution

curl is vulnerable to arbitrary code execution attacks. The vulnerability exists as multiple integer overflows in the 1 curlescape, 2 curleasyescape, 3 curlunescape, and 4 curleasyunescape functions in libcurl before 7.50.3 allow attackers to have unspecified impact via a string of length...

Cookie Leak

libcurl.so is vulnerable to cookie leak. A remote attacker is able to set or send arbitrary cookies for certain sites. libcurl.so parses IP addresses similar to domain names, where a site with an IP address of 192.168.0.1 can set or send cookies for another site ending with .168.0.1...

Information Disclosure

libcurl is vulnerable to information disclosure. The tailMatch function in cookie.c does not properly matched when sending cookies, allowing remote attackers to steal cookies via a matchign suffix in the domain of the URL...

Authentication Bypass

libcurl.so is vulnerable to authentication bypasses. The library re-uses NTLM connections, allowing a malicious user to reuse a connection to bypass authentication...

EulerOS 2.0 SP3 : curl (EulerOS-SA-2018-1401)

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...

Security Bulletin: The Community Edition of IBM ILOG CPLEX Optimization Studio is affected by a vulnerability in libcurl (CVE-2018-16840)

Summary The Community Edition of IBM ILOG CPLEX Optimization Studio on Windows platform only has addressed the following vulnerability: libcurl is vulnerable to a denial of service. Vulnerability Details CVEID: CVE-2018-16840 DESCRIPTION: cURL is vulnerable to a denial of service, caused by a hea...

curl, libcurl, nss security update

CentOS Errata and Security Advisory CESA-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...

curl: NTLM buffer overflow via integer overflow

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: printf floating point buffer overflow

curl before version 7.52.0 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 application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks...

curl: FTP wildcard out of bounds read

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...

curl: HTTP authentication leak in redirects

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...

curl: Use of connection struct after free

A use-after-free flaw was found in libcurl. When invoking curleasyperform after cleaning up a multi session, an application can be tricked into using libcurl to connect to a malicious server, allowing an attacker to potentially execute arbitrary code. The highest threat from this vulnerability is...

curl: Re-using connection with wrong client cert

It was found that the libcurl library did not check the client certificate when choosing the TLS connection to reuse. 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...

curl: escape and unescape integer overflows

Multiple integer overflow flaws leading to heap-based buffer overflows were found in the way curl handled escaping and unescaping of data. An attacker could potentially use these flaws to crash an application using libcurl by sending a specially crafted input to the affected libcurl functions...

CURL-CVE-2018-16840 use after free in handle close

libcurl contains a heap use after free flaw in code related to closing an easy handle. When closing and cleaning up an "easy" handle in the Curlclose function, the library code first frees a struct without clearing the pointer and might then subsequently erroneously write to a struct field within...
