Hi, I'd like to propose a row of smaller fixes where code is noted down a bit questionable. SAP's quality process requires that we fix these in our internal delivery, and I Would like to share my fixes with openJdk. Some of these fixes are of more theoretical nature as how I understand the code paths never allow the problematic situation, but fixing it nevertheless assures that nothing is overseen if the code changes. Most changes are in libawt_xawt, some are in libsunec.
I'd appreciate a review: http://cr.openjdk.java.net/~goetz/wr16/8170525-awt/webrev.01/ Changes in detail: awt_InputMethod.c: One might overrun the 100 byte fixed-size string statusWindow->status by copying text->string.multi_byte without checking the length. gtk3_interface.c: This less-than-zero comparison of an unsigned value is never true. Using uninitialized value color. Field color.alpha is uninitialized. E.g. used at gtk3_interface.c:2287. XToolkit.c Using uninitialized value ret_timeout. E.g. in XToolkit.c:6809. XWindow.c Argument is incompatible with corresponding format string conversion. splashscreen_sys.c Overflowed or truncated value (or a value computed from an overflowed or truncated value) (gdk_scale > 0) ? native_scale * (double)gdk_scale : native_scale used as return value. ec.c Using uninitialized value k.dp when calling mp_clear. ecdecode.c You might overrun the 291 byte fixed-size string genenc by copying curveParams->geny without checking the length. Added sanity check before doing the string concatenation. ecl_mult.c Using uninitialized value kt.flag when calling *group->point_mul. (The function pointer resolves to ec_GF2m_pt_mul_mont.) mpi.c Using uninitialized value s. Field s.flag is uninitialized when calling s_mp_exch. Using uninitialized value tmp. Field tmp.flag is uninitialized when calling s_mp_exch Using uninitialized value t.dp when calling mp_clear. p11_mutex.c Using uninitialized value *ckpInitArgs. Field ckpInitArgs->flags is uninitialized when calling memcpy. DataBufferNative.c Using uninitialized value lockInfo.rasBase when calling BN_GetPixelPointer. fontpath.c You might overrun the 512 byte fixed-size string fontDirPath by copying DirP->name[index] without checking the length.
