Astra Linux – Vulnerability in curl

There is a vulnerability in the handling of certificate validation in curl v8.1.0, particularly in how wildcard patterns are matched when listed as “Subject Alternative Name” in TLS server certificates. Curls can be modified to use its own name matching function for TLS, rather than the one...

There is an information disclosure vulnerability in curl v8.1.0 when performing HTTPS transfers. libcurl may incorrectly use the read callback CURLOPTREADFUNCTION to request data to be sent, even when the CURLOPTPOSTFIELDS option is set. This occurs if the same handle was previously used to issue...

Astra Linux – Vulnerability in curl

This flaw allows an attacker to insert cookies into a running program using libcurl, provided that certain conditions are met. Libcurl performs transfers. In its API, an application creates “easy handles”—individual handles used for single transfers. Libcurl provides a function called...

Astra Linux – Vulnerability in curl

In versions 7.7 through 7.76.1 of curl, there is an information disclosure issue when the -t command-line option, referred to as CURLOPTTELNETOPTIONS in libcurl, is used to send variable=content pairs to TELNET servers. This issue arises due to a flaw in the option parser for sending NEWENV...

Curl versions 7.62.0 through 7.70.0 are vulnerable to an information disclosure vulnerability that can result in a partial password being leaked over the network and to the DNS servers...

Astra Linux – Vulnerability in curl

A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port. In this way, the malicious server can potentially enable curl to extract information about services that would otherwise be private and undisclosed. This could...

Astra Linux – Vulnerability in curl

There is a vulnerability in input validation in curl 8.0. During communication using the TELNET protocol, this vulnerability may allow an attacker to submit maliciously crafted user names and “telnet options” during server negotiation. The lack of proper input scrubbing allows an attacker to send...

Astra Linux – Vulnerability in curl

libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL. As a result, it does not detect impostor attacks or man-in-the-middle attacks...

Astra Linux - уязвимость в curl

libcurl supports pinning of the server certificate public key for HTTPS transfers. Due to an omission, this check is not performed when connecting with QUIC for HTTP/3, when the TLS backend is wolfSSL. The documentation states that this option works with wolfSSL, but does not specify that it does...

Astra Linux – Vulnerability in curl

There is a path traversal vulnerability in the 8.0.0 SFTP implementation of curl. This vulnerability causes the tilde character to be incorrectly replaced when used as a prefix in the first path element. Additionally, the tilde is intended to be used as the first element to indicate a path relati...

Astra Linux – Vulnerability in curl

There is a vulnerability in curl v7.88.0 where resource allocation without limits or throttling exists. This vulnerability stems from the “chained” HTTP compression algorithms. This means that a server’s response can be compressed multiple times, possibly using different algorithms. The number of...

Astra Linux – Vulnerability in curl

An integer overflow vulnerability exists in the tooloperate.c file of curl 7.65.2, which can be exploited by using a large value as the retry delay. NOTE: Many reports indicate that this does not have a direct security impact on the curl user. However, it may in theory cause a denial of service t...

Astra Linux – Vulnerability in curl

When curl 7.84.0 performs FTP transfers secured by krb5, it incorrectly handles message verification failures. This flaw allows a Man-In-The-Middle attack to go unnoticed, and even enables the attacker to inject data into the client’s system...

Astra Linux – Vulnerability in curl

When performing HTTPS transfers, libcurl may incorrectly use the read callback CURLOPTREADFUNCTION to request data to be sent, even when the CURLOPTPOSTFIELDS option has been set. This occurs if the same handle was previously used to issue a PUT request that utilized that callback. This flaw may...

Astra Linux – Vulnerability in curl

A poorly protected credentials vulnerability exists in curl 4.9, and versions including curl 7.82.0 are also affected. This vulnerability could allow attackers to extract credentials when using HTTPS redirections with authentication. As a result, credentials may be leaked to other services that...

Astra Linux – Vulnerability in curl

When the curl command is used to retrieve content using the Metalink feature, and a username and password are used to download the Metalink XML file, those same credentials are then passed to each server from which the curl command will attempt to download or retrieve the content. This often...

Astra Linux – Vulnerability in curl

Due to the use of a dangling pointer, libcurl versions 7.29.0 through 7.71.1 can use the wrong connection when sending data...

Astra Linux – Vulnerability in curl

A user can specify that curl = 7.20.0 and = 7.78.0 requires a successful upgrade to TLS when communicating with IMAP, POP3, or FTP servers. This is achieved by using the --ssl-reqd option on the command line, or setting CURLOPT USESSL to CURLUSESSLCONTROL or CURLUSESSLALL with licurl. This...

Astra Linux – Vulnerability in curl

curl 7.1.1 up to and including 7.75.0 is vulnerable to a “Exposure of Private Personal Information to an Unauthorized Actor” by leaking credentials in the HTTP Referer: header. libcurl does not remove user credentials from the URL when automatically filling in the Referer: HTTP request header fie...

Astra Linux – Vulnerability in curl

Curl versions 7.41.0 through 7.73.0 are vulnerable to a flaw related to improper checks for certificate revocation, due to insufficient verification of the OCSP response...
