CVE-2018-16840
CRITICAL9.8EPSS 0.29%發布日:2018/10/31修改日:2026/4/28
描述
A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the `Curl_close()` function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.
受影響套件(2)
- Alpine/curlfrom 0, < 7.62.0-r0
- Debian/curlfrom 0, < 7.62.0-1
