TITLE

curl  Vulnerability in Certificate Verification

DESCRIPTION

curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to insufficient verification of the OCSP response. curl Contains a certificate validation vulnerability.Information may be tampered with. HAXX libcurl is an open source client-side URL transfer library developed by Haxx (HAXX) in Sweden. The product supports protocols such as FTP, SFTP, TFTP and HTTP. A security vulnerability exists in libcurl that could be exploited by an attacker to read or write data in a session by acting as a man-in-the-middle through low-level OCSP authentication on libcurl. CVE-2020-8177 sn reported that curl could be tricked by a malicious server into overwriting a local file when using th -J (--remote-header-name) and -i (--include) options in the same command line. CVE-2020-8231 Marc Aldorasi reported that libcurl might use the wrong connection when an application using libcurl's multi API sets the option CURLOPT_CONNECT_ONLY, which could lead to information leaks. CVE-2020-8284 Varnavas Papaioannou reported that a malicious server could use the PASV response to trick curl into connecting back to an arbitrary IP address and port, potentially making curl extract information about services that are otherwise private and not disclosed. CVE-2020-8285 xnynx reported that libcurl could run out of stack space when using tha FTP wildcard matching functionality (CURLOPT_CHUNK_BGN_FUNCTION). CVE-2020-8286 It was reported that libcurl didn't verify that an OCSP response actually matches the certificate it is intended to. CVE-2021-22876 Viktor Szakats reported that libcurl does not strip off user credentials from the URL when automatically populating the Referer HTTP request header field in outgoing HTTP requests. CVE-2021-22890 Mingtao Yang reported that, when using an HTTPS proxy and TLS 1.3, libcurl could confuse session tickets arriving from the HTTPS proxy as if they arrived from the remote server instead. This could allow an HTTPS proxy to trick libcurl into using the wrong session ticket for the host and thereby circumvent the server TLS certificate check. For the stable distribution (buster), these problems have been fixed in version 7.64.0-4+deb10u2. We recommend that you upgrade your curl packages. For the detailed security status of curl please refer to its security tracker page at: https://security-tracker.debian.org/tracker/curl Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEBsId305pBx+F583DbwzL4CFiRygFAmBkQCoACgkQbwzL4CFi Ryg6Gg/+LqhhJ8+D7skevVkYzxHzdH2yT/XMeoYp0D37yHmEfH9PyjXwfplG+XEw /xwFRBK8qxD1ja+rQddYyeTvi1OMnMgMS3UsRHlfeMnLxh2+oHnvHDYG848npUEZ Rq4YFoc/n9YTAJZP/G4oiuBeXqH2Sqa5hSNT6VrYfRciCxkYnzA78b85KpI8aYyR lhfiJMNpwrqDbt/QzblpELBkGMIV402VeiqDwHfcVzm2E810xXQNLvPMbWtvDYkA TSrNsdqfuFr1tuQSZY6CGSWEyXtB/tOo8+pvUixlJMBWJMl5TXEcJkD5ckehx0yb C3n9yapfklxHiG9lD4zwwIJDqd3Y4SxdDiSlUC4OhdvpwniMygX0S3ICaPA4iac/ cWanml0Fop3OmRy+vQURTd3sADoT5HoRSUXZVU+HdTrRaEt2xs5okZkWSd3yr4Ux i+HgjUAFkkk8DLRB68Bbpx1LGxFGQT7L8yd4wsWINXlzASIP1A5dnNfE5w0VWOHG 3KDq47wNfjuiZC8GXW+HQCxz5MijnS8Y/Egl0OozNFDwEitNBZEsIjpZaZBdZIwi UFfcK7+u/y/TRY54rA4erkdcHFwpYW5EZVGdb7Z+WPWVlzw0ImXrM68LSAhHQaqW 1Hx4VwwwTsMIPnrx2kriRiiDPOW1r5Kip3yHa+QZLedSRGibQWk= =001T -----END PGP SIGNATURE----- . 8) - aarch64, ppc64le, s390x, x86_64 3.
