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
A authentication bypass vulnerability exists in libcurl version 8.0.0, particularly in the connection reuse feature. This vulnerability allows for the reuse of previously established connections with incorrect user permissions, due to a failure to check for changes in the CURLOPTGSSAPIDELEGATION...
Astra Linux – Vulnerability in curl
When curl is used to retrieve and parse cookies from an HTTPS server, it accepts cookies using control codes that, when sent back to an HTTP server later, may cause the server to return 400 responses. This effectively allows a “sister site” to deny service to all other sibling sites...
Astra Linux – Vulnerability in curl
When curl version 7.20.0 or later connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can send multiple responses at once, which are cached by curl. In this case, curl upgrades to TLS, but it does not discard the cached responses. Instead, it...
Astra Linux – Vulnerability in curl
curl 7.84.0 supports “chained” HTTP compression algorithms, which means that a server response can be compressed multiple times, possibly using different algorithms. The number of allowable “links” in this “decompression chain” is unlimited, allowing a malicious server to insert virtually an...
Astra Linux – Vulnerability in curl
libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse, if one of them matches the setup. Due to errors in the logic, the config matching function did not take ‘issuercert’ into account, and it compared the involved paths case insensitively, which could...
Astra Linux – Vulnerability in curl
This flaw allows a malicious HTTP server to set “super cookies” using curl, which are then transmitted back to multiple origins beyond what is allowed or possible. This enables a site to set cookies that are then sent to different and unrelated sites and domains. The attack exploits a flaw in...
Astra Linux – Vulnerability in curl
When asked to use a .netrc file for credentials and to follow HTTP redirects, curl could leak the password used for the first host to the followed-to host under certain circumstances. This flaw only manifests itself if the netrc file has an entry that matches the redirect target hostname, but the...
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
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 an OAuth2 bearer token is used for an HTTPS transfer, and that transfer performs a cross-protocol redirect to a second URL that uses an IMAP, LDAP, POP3, or SMTP scheme, curl may incorrectly pass the bearer token to the new target host...
Astra Linux – Vulnerability in curl
There is a vulnerability in curl version 7.87.0 where it is possible to exploit the memory reclamation mechanism. In this vulnerability, curl can be instructed to tunnel virtually all protocols it supports through an HTTP proxy. HTTP proxies can and often do deny such tunnel operations. When curl...
Astra Linux – Vulnerability in curl
When performing multi-threaded LDAPS transfers LDAP over TLS with libcurl, changing TLS options in one thread will inadvertently change them globally, and thus may also affect other concurrently running transfers. Disabling certificate verification for a specific transfer can unintentionally...
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
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
There is an improper authentication vulnerability in curl versions 7.33.0 through and including 7.82.0. This vulnerability may allow for the reuse of OAUTH2-authenticated connections without ensuring that the connection was authentically verified with the same credentials used for this transfer...
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
When the curl command is used to retrieve content using the Metalink feature, and a user name 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...
