Fixes the following security issues: CVE-2017-13089: The http.c:skip_short_body() function is called in some circumstances, such as when processing redirects. When the response is sent chunked, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to skip the chunk in pieces of 512 bytes by using the MIN() macro, but ends up passing the negative chunk length to connect.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument. CVE-2017-13090: The retr.c:fd_read_body() function is called when processing OK responses. When the response is sent chunked, the chunk parser uses strtol() to read each chunk's length, but doesn't check that the chunk length is a non-negative number. The code then tries to read the chunk in pieces of 8192 bytes by using the MIN() macro, but ends up passing the negative chunk length to retr.c:fd_read(). As fd_read() takes an int argument, the high 32 bits of the chunk length are discarded, leaving fd_read() with a completely attacker controlled length argument. The attacker can corrupt malloc metadata after the allocated buffer. Drop now upstreamed patch and change to .tar.lz as .tar.xz is no longer available. Also add a hash for the license file while we're at it. Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
