[ASA-201811-6] libcurl-gnutls: arbitrary code execution
Arch Linux Security Advisory ASA-201811-6 ========================================= Severity: High Date : 2018-11-06 CVE-ID : CVE-2018-16840 Package : libcurl-gnutls Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-799 Summary ======= The package libcurl-gnutls before version 7.62.0-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 7.62.0-1. # pacman -Syu "libcurl-gnutls>=7.62.0-1" The problem has been fixed upstream in version 7.62.0. Workaround ========== None. Description =========== 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. Impact ====== A malicious remote server might be able to execute arbitrary commands by closing the connection from a client using easy handlers.
