CVE-2016-7141 [HIGH] curl vulnerabilities
Title: curl vulnerabilities
Summary: Several security issues were fixed in curl.
It was discovered that curl incorrectly reused client certificates when
built with NSS. A remote attacker could possibly use this issue to hijack
the authentication of a TLS connection. (CVE-2016-7141)
Nguyen Vu Hoang discovered that curl incorrectly handled escaping certain
strings. A remote attacker could possibly use this issue to cause curl to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2016-7167)
It was discovered that curl incorrectly handled storing cookies. A remote
attacker could possibly use this issue to inject cookies for arbitrary
domains in the cookie jar. (CVE-2016-8615)

CVE-2016-8623 curl: Use-after-free via shared cookies
bugzilla·2016-10-25·CVSS 3.3
CVE-2016-8623 [LOW] CVE-2016-8623 curl: Use-after-free via shared cookies
CVE-2016-8623 curl: Use-after-free via shared cookies
libcurl explicitly allows users to share cookies between multiple easy handles
that are concurrently employed by different threads.
When cookies to be sent to a server are collected, the matching function
collects all cookies to send and the cookie lock is released immediately
afterwards. That funcion however only returns a list with *references* back to
the original strings for name, value, path and so on. Therefore, if another
thread quickly takes the lock and frees one of the original cookie structs
together with its strings, a use-after-free can occur and lead to information
disclosure. Another thread can also replace the contents of the cookies from
separate HTTP responses or API calls.
