The vulnerability of the tftp_receive_packet() function in the libcurl library, related to the issue of outputting operations beyond the buffer in memory, allows a attacker to cause a service failure or execute arbitrary code.

The vulnerability of the tftpreceivepacket function in the libcurl library is related to the execution of operations outside of the buffer in memory. Exploiting this vulnerability could allow an attacker to cause a service failure or execute arbitrary code...

Arbitrary Code Execution

libcurl.so is vulnerable to arbitrary code execution. A heap-based buffer overflow in the function tftpreceivepacket that receives data from a TFTP server could potentially allow an attacker to execute arbitrary code by sending an OACK without the BLKSIZE option, when a BLKSIZE smaller than 512...

DEBIAN-CVE-2018-16890

libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages lib/vauth/ntlm.c:ntlmdecodetype2target does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that...

CURL-CVE-2019-3822 NTLMv2 type-3 header stack buffer overflow

libcurl contains a stack based buffer overflow vulnerability. The function creating an outgoing NTLM type-3 header lib/vauth/ntlm.c:Curlauthcreatentlmtype3message, generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from...

NTLMv2 type-3 header stack buffer overflow

libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages lib/vauth/ntlm.c:ntlmdecodetype2target does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that...

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...

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...

libcurl Buffer Overflow Vulnerability

libcurl is a free and easy to use client-side URL transport library . A buffer overflow vulnerability exists in lib/curlntlmcore.c in libcurlntlmcoremknthash in Libcurl 7.15.4 - 7.61.0. A remote user can exploit this vulnerability by sending a specially crafted NTLM authentication password to...

Cookie Injection

libcurl.so is vulnerable to cookie injection attacks. A malicious user can inject new cookies by writing to a cookie jar file that is later read and used for other requests as it is treated by the library as a different cookie...

Insecure Defaults

libcurl.so is vulnerable to insecure defaults. The library re-uses connections rather than create new connections, allowing a malicious user to connect to other users by sending requests through a re-used connection, leading to an authentication bypass in certain connections that require...

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...

Denial Of Service (DoS)

libcurl.so is vulnerable to denial of service DoS attacks. The attacks exist due to performing multiplication without validating the size of buffer allocation causing an out-of-bounds write...

Invalid Encoding

libcurl.so is vulnerable to invalid encoding. The library does not properly parse the authority component of the URL in a curl request, causing the request to be sent to a different URL...

Use-After-free Vulnerability

libcurl.so is vulnerable to use after-free vulnerability. The attack is possible when cookies are shared among many easy handles simultaneously used in different threads...

Haxx curl 'curl_smtp_escape_eob' function heap 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 heap buffer overflow vulnerability exists in the...

Buffer Overread

libcurl.so is vulnerable to buffer overread attacks. The vulnerability exists due to the lack of bound checking to ensure that reads are unable to exceed the buffer...

Information Disclosure

libcurl.so is vulnerable to information disclosures. When running with the --write-out command, the application skips the end of the string zero byte if the string ends with % or \\ , causing the application to read out of the buffer and disclose sensitive information...

CVE-2016-9594

curl before version 7.52.1 is vulnerable to an uninitialized random in libcurl's internal function that returns a good 32bit random value. Having a weak or virtually non-existent random value makes the operations that use it vulnerable...

ALPINE-CVE-2018-1000005

libcurl 7.49.0 to and including 7.57.0 contains an out bounds read in code handling HTTP/2 trailers. It was reported https://github.com/curl/curl/pull/2231 that reading an HTTP/2 trailer could mess up future trailers since the stored size was one byte less than required. The problem is that the...
