CURL-CVE-2016-8615
No affected components available
If cookie state is written into a cookie jar file that is later read back and used for subsequent requests, a malicious HTTP server can inject new cookies for arbitrary domains into said cookie jar.
The issue pertains to the function that loads cookies into memory, which reads
the specified file into a fixed-size buffer in a line-by-line manner using the
fgets() function. If an invocation of fgets() cannot read the whole line
into the destination buffer due to it being too small, it truncates the
output. This way, a long cookie (name + value) sent by a malicious server
would be stored in the file and subsequently that cookie could be read
partially and crafted correctly, it could be treated as a different cookie for
another server.
