{"id":"USN-5702-1","summary":"curl vulnerabilities","details":"Robby Simpson discovered that curl incorrectly handled certain POST\noperations after PUT operations. This issue could cause applications using\ncurl to send the wrong data, perform incorrect memory operations, or crash.\n(CVE-2022-32221)\n\nHiroki Kurosawa discovered that curl incorrectly handled parsing .netrc\nfiles. If an attacker were able to provide a specially crafted .netrc file,\nthis issue could cause curl to crash, resulting in a denial of service.\nThis issue only affected Ubuntu 22.10. (CVE-2022-35260)\n\nIt was discovered that curl incorrectly handled certain HTTP proxy return\ncodes. A remote attacker could use this issue to cause curl to crash,\nresulting in a denial of service, or possibly execute arbitrary code. This\nissue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10. (CVE-2022-42915)\n\nHiroki Kurosawa discovered that curl incorrectly handled HSTS support\nwhen certain hostnames included IDN characters. A remote attacker could\npossibly use this issue to cause curl to use unencrypted connections. This\nissue only affected Ubuntu 22.04 LTS, and Ubuntu 22.10.
