curl: Use-after-free via shared cookies

A flaw was found in curl before version 7.51.0. The way curl handles cookies permits other threads to trigger a use-after-free leading to information disclosure...

curl: Double-free in krb5 code

The function readdata in security.c in curl before version 7.51.0 is vulnerable to memory double free...

curl: --write-out out of bounds read

The ourWriteOut function in toolwriteout.c in curl 7.53.1 might allow 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 leads to a...

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: TLS session resumption client cert bypass

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...

curl: Invalid URL parsing with '#'

curl before version 7.51.0 doesn't parse the authority component of the URL correctly when the host name part ends with a '' character, and could instead be tricked into connecting to a different host. This may have security implications if you for example use an URL parser that follows the RFC t...

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: RTSP RTP buffer over-read

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...

curl: Out-of-bounds heap read when missing RTSP headers allows information leak or denial of service

curl version curl 7.20.0 to and including curl 7.59.0 contains a CWE-126: 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.. This vulnerability appears to have...

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...

curl: Double-free in curl_maprintf

The libcurl API function called curlmaprintf before version 7.51.0 can be tricked into doing a double-free due to an unsafe sizet multiplication, on systems using 32 bit sizet variables...

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: Out-of-bounds write via unchecked multiplication

The base64 encode function in curl before version 7.51.0 is prone to a buffer being under allocated in 32bit systems if it receives at least 1Gb as input via CURLOPTUSERNAME...

curl: curl_getdate out-of-bounds read

The curlgetdate function in curl before version 7.51.0 is vulnerable to an out of bounds read if it receives an input with one digit short...

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: Case insensitive password comparison

A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped...

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: 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...
