+Subject: [PATCH] Fix integer overflow in _TIFFCheckMalloc() and other
+ implementation-defined behaviour (CVE-2019-14973)
+
+_TIFFCheckMalloc()/_TIFFCheckRealloc() used a unsafe way to detect overflow
+in the multiplication of nmemb and elem_size (which are of type tmsize_t, thus
+signed), which was especially easily triggered on 32-bit builds (with recent
+enough compilers that assume that signed multiplication cannot overflow, since
+this is undefined behaviour by the C standard). The original issue which lead to
+this fix was trigged from tif_fax3.c
+
+There were also unsafe (implementation defied), and broken in practice on 64bit
+builds, ways of checking that a uint64 fits of a (signed) tmsize_t by doing
+(uint64)(tmsize_t)uint64_var != uint64_var comparisons. Those have no known
+at that time exploits, but are better to fix in a more bullet-proof way.
+Or similarly use of (int64)uint64_var <= 0.
