Mandriva Linux Security Advisory 2009-142 – Multiple security vulnerabilities has been identified and fixed in jasper. The jpc_qcx_getcompparms function in jpc/jpc_cs.c for the JasPer JPEG-2000 library (libjasper) before 1.900 allows remote user-assisted attackers to cause a denial of service (crash) and possibly corrupt the heap via malformed image files, as originally demonstrated using imagemagick convert. Multiple integer overflows in JasPer 1.900.1 might allow context-dependent attackers to have an unknown impact via a crafted image file, related to integer multiplication for memory allocation. The jas_stream_tmpfile function in libjasper/base/jas_stream.c in JasPer 1.900.1 allows local users to overwrite arbitrary files via a symlink attack on a tmp.XXXXXXXXXX temporary file. Buffer overflow in the jas_stream_printf function in libjasper/base/jas_stream.c in JasPer 1.900.1 might allow context-dependent attackers to have an unknown impact via vectors related to the mif_hdr_put function and use of vsprintf. The updated packages have been patched to prevent this. Packages for 2008.0 are being provided due to extended support for Corporate products.
