The vulnerability of the curl_url_set() function in the libcurl library allows a hacker to trigger a service failure.

The vulnerability of the curlurlset function in the libcurl library is related to integer overflow. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

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...

curl: Race condition with CURL_LOCK_DATA_CONNECT can cause connections to be used at the same time

Summary: We've seen race conditions when using CURLLOCKDATACONNECT in libcurl where sometimes two different threads using two different easy handles ends up sharing the same connection pointer at the same time. This causes UAFs and double frees when both threads are freeing items on the same...

CVE-2016-5421

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...

CVE-2017-1000254

libcurl may read outside of a heap allocated buffer when doing FTP. When libcurl connects to an FTP server and successfully logs in anonymous or not, it asks the server for the current directory with the PWD command. The server then responds with a 257 response containing the path, inside double...

CVE-2016-7141

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...

CVE-2016-5419

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...

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...

According to the version of the curl packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability : - A heap buffer overflow in the TFTP receiving code allows for DoS or arbitrary code execution in libcurl versions 7.19.4...

EulerOS 2.0 SP2 : curl (EulerOS-SA-2019-1839)

According to the version of the curl packages installed, the EulerOS installation on the remote host is affected by the following vulnerability : - A heap buffer overflow in the TFTP receiving code allows for DoS or arbitrary code execution in libcurl versions 7.19.4 through 7.64.1.CVE-2019-5436...

Arbitrary Code Execution

libcurl.so is vulnerable to arbitrary code execution. A double-free occurs when a malicious server claims to send a large block that results in the realloc function call to fail. The vulnerability exists when curl uses kerberos over FTP, and can be exploited by an attacker to execute arbitrary co...

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...

CURL-CVE-2019-5482 TFTP small blocksize heap buffer overflow

libcurl contains a heap buffer overflow in the function tftpreceivepacket that receives data from a TFTP server. It can call recvfrom with the default size for the buffer rather than with the size that was used to allocate it. Thus, the content that might overwrite the heap memory is controlled b...

curl -- multiple vulnerabilities

curl security problems: CVE-2019-5481: FTP-KRB double-free libcurl can be told to use kerberos over FTP to a server, as set with the CURLOPTKRBLEVEL option. During such kerberos FTP data transfer, the server sends data to curl in blocks with the 32 bit size of each block first and then that amoun...

curl/libcURL CVE-2019-5482 Heap Buffer Overflow Vulnerability

Description curl/libcURL is prone a heap-based buffer-overflow vulnerability. An attacker can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely result in denial-of-service conditions. libcurl versions 7.19.4 through 7.65.3...
