moderate: cairo/curl security update
moderate
An update for cairo/curl is now available for NewStart CGSL MAIN 6.06.
NewStart Security has rated this update as having a security impact of moderate. A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
cairo: Cairo is a 2D graphics library designed to provide high-quality display and print output. Currently supported output targets include the X Window System, in-memory image buffers, and image files (PDF, PostScript, and SVG). Cairo is designed to produce consistent output on all output media while taking advantage of display hardware acceleration when available.
curl: curl is a command line tool for transferring data with URL syntax, supporting FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS, FILE, IMAP, SMTP, POP3 and RTSP. curl supports SSL certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form based upload, proxies, cookies, user+password authentication (Basic, Digest, NTLM, Negotiate, kerberos...), file transfer resume, proxy tunneling and a busload of other useful tricks.
Security Fix(es):
cairo: A flaw was found in cairo's image-compositor.c. This flaw allows an attacker who can provide a crafted input file to cairo's image-compositor (for example, by convincing a user to open a file in an application using cairo, or if an application uses cairo on untrusted input) to cause a stack buffer overflow -> out-of-bounds WRITE. The highest impact from this vulnerability is to confidentiality, integrity, as well as system availability.(CVE-2020-35492)
cairo: bugfix
curl: A vulnerability was found in curl. This security flaw allows leaking credentials to other servers when it follows redirects from auth-protected HTTP(S) URLs to other protocols and port numbers.(CVE-2022-27774)
curl: A vulnerability was found in curl. This issue occurs because curl can reuse a previously created connection even when a TLS or SSH-related option is changed that should have prohibited reuse. This flaw leads to an authentication bypass, either by mistake or by a malicious actor.(CVE-2022-27782)
curl: A vulnerability was found in curl. This issue occurs because it mishandles message verification failures when curl does FTP transfers secured by krb5. This flaw makes it possible for a Man-in-the-middle attack to go unnoticed and allows data injection into the client.(CVE-2022-32208)
curl: A vulnerability was found in curl. This issue occurs because the number of acceptable "links" in the "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps. This flaw leads to a denial of service, either by mistake or by a malicious actor.(CVE-2022-32206)
curl: A flaw was found in curl. The flaw lies in how curl handles cached or pipelined responses that it receives from either a IMAP, POP3, SMTP or FTP server before the TLS upgrade using STARTTLS. In such a scenario curl even after upgrading to TLS would trust these cached responses treating them as valid and authenticated and use them. An attacker could potentially use this flaw to carry out a Man-In-The-Middle attack. The highest threat from this vulnerability is to data confidentiality.(CVE-2021-22947)
curl: A flaw was found in curl. This flaw lies in the --ssl-reqd option or related settings in libcurl. Users specify this flag to upgrade to TLS when communicating with either IMAP, POP3 or a FTP server. An attacker controlling such servers could return a crafted response which could lead to curl client continue its operation without TLS encryption leading to data being transmitted in clear text over the network. The highest threat from this vulnerability is to data confidentiality.(CVE-2021-22946)
curl: A flaw was found in libcurl in the way libcurl handles previously used connections without accounting for 'issuer cert' and comparing the involved paths case-insensitively. This flaw allows libcurl to use the wrong connection. The highest threat from this vulnerability is to confidentiality.(CVE-2021-22924)
curl: A vulnerability was found in curl. This security flaw allows leak authentication or cookie header data on HTTP redirects to the same host but another port number. Sending the same set of headers to a server on a different port number is a problem for applications that pass on custom `Authorization:` or `Cookie:`headers. Those headers often contain privacy-sensitive information or data.(CVE-2022-27776)
curl: A flaw was found in curl in the way curl handles a file hash mismatch after downloading content using the Metalink feature. This flaw allows malicious actors controlling a hosting server to trick users into downloading malicious content. The highest threat from this vulnerability is to integrity.(CVE-2021-22922)
curl: A flaw was found in curl. Overwriting local files is possible when using a certain combination of command line options. Requesting content from a malicious server could lead to overwriting local files with compromised files leading to unknown effects. The highest threat from this vulnerability is to file integrity.(CVE-2020-8177)
curl: A vulnerability was found in curl. This security flaw allows reusing OAUTH2-authenticated connections without properly ensuring that the connection was authenticated with the same credentials set for this transfer. This issue leads to an authentication bypass, either by mistake or by a malicious actor.(CVE-2022-22576)
curl: A flaw was found in curl in the way curl handles credentials when downloading content using the Metalink feature. This flaw allows malicious actors controlling a hosting server to gain access to credentials provided while downloading content without the user's knowledge. The highest threat from this vulnerability is to confidentiality.(CVE-2021-22923)
curl: bugfix
