  "details" : [ "Calling `curl_easy_pause()` within the event-based `CURLMOPT_SOCKETFUNCTION`\ncallback triggers a use-after-free vulnerability, where libcurl attempts to\nstore a flag using a dangling struct pointer immediately after that pointer's\nmemory has been freed.", "A flaw was found in libcurl. When `curl_easy_pause()` is called within the event-based `CURLMOPT_SOCKETFUNCTION` callback, a use-after-free vulnerability is triggered. This occurs because libcurl attempts to store a flag using a pointer to memory that has already been freed. An attacker could potentially exploit this to cause a denial of service or execute arbitrary code." ],
  "statement" : "This Important flaw in libcurl stems from a use-after-free vulnerability when `curl_easy_pause()` is called within the `CURLMOPT_SOCKETFUNCTION` callback. This could allow an attacker to achieve denial of service or arbitrary code execution without requiring user interaction or elevated privileges. While dependent on a specific application implementation, the broad adoption of libcurl means Red Hat products leveraging this callback pattern could be affected.",
