4 issues left for the package maintainer to handle:
  • CVE-2021-22898: (needs triaging) curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol.
  • CVE-2021-22924: (needs triaging) libcurl keeps previously used connections in a connection pool for subsequenttransfers 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 lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate.
  • CVE-2021-22946: (needs triaging) A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network.
  • CVE-2021-22947: (needs triaging) When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server.

You can find information about how to handle these issues in the security team's documentation.

  • CVE-2021-22945: (needs triaging) When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.

testing migrations
  • This package is part of the ongoing testing transition known as auto-openssl. Please avoid uploads unrelated to this transition, they would likely delay it and require supplementary work from the release managers. On the other hand, if your package has problems preventing it to migrate to testing, please fix them as soon as possible. You can probably find supplementary information in the debian-release archives or in the corresponding release.debian.org bug.
  • excuses:
    • Migration status: Blocked. Can't migrate due to a non-migratable dependency. Check status below.
    • Blocked by: openssl
    • Migration status for curl (7.83.0-1 to 7.83.1-1): BLOCKED: Cannot migrate due to another item, which is blocked (please check which dependencies are stuck)
    • Issues preventing migration:
    • ∙ ∙ Depends: curl openssl (not considered)
    • ∙ ∙ Invalidated by dependency
    • Additional info:
    • ∙ ∙ Piuparts tested OK - https://piuparts.debian.org/sid/source/c/curl.html
    • ∙ ∙ autopkgtest for libreoffice/blocked-on-ci-infra: arm64: Ignored failure, i386: Ignored failure, ppc64el: Ignored failure, s390x: Ignored failure
    • ∙ ∙ 8 days old (needed 5 days)
    • Not considered
