CVE-2014-8157: Use After Free
First published: Tue Jan 06 2015(Updated: )
oCERT reports an issue in jasper discovered by pyddeh: """ jpc_dec.c:1204: dec->numhtiles = JPC_CEILDIV(dec->xend - dec->tilexoff, dec->tilewidth); dec->numvtiles = JPC_CEILDIV(dec->yend - dec->tileyoff, dec->tileheight); dec->numtiles = dec->numhtiles * dec->numvtiles; if (!(dec->tiles = jas_malloc(dec->numtiles * sizeof(jpc_dec_tile_t)))) { return -1; } the dec->XXX in JPC_CEILDIV are all directly from the codestream, so dec->numtiles can be 0. In that case, the minimum-sized chunk returned by malloc can, depending on the code stream, be used later. I think this can cause the same problems as a use after free. Fix proposal: if ( dec->numtiles == 0 || !(dec->tiles = jas_malloc(dec->numtiles * sizeof(jpc_dec_tile_t)))) { return -1; } """ Acknowledgement: Red Hat would like to thank oCERT for reporting this issue. oCERT acknowledges pyddeh as the original reporter.
