Debian DLA-211-1 : curl security update
Medium Nessus Plugin ID 83143
SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral vulnerabilities were discovered in cURL, an URL transfer library :
NTLM-authenticated connections could be wrongly reused for requests without any credentials set, leading to HTTP requests being sent over the connection authenticated as a different user. This is similar to the issue fixed in DSA-2849-1.
When doing HTTP requests using the Negotiate authentication method along with NTLM, the connection used would not be marked as authenticated, making it possible to reuse it and send requests for one user over the connection authenticated as a different user.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected packages.
