Buffer overflow in the wvHandleDateTimePicture function in wv library (wvWare) 0.7.4 through 0.7.6 and 1.0.0 allows remote attackers to execute arbitrary code via a document with a long DateTime field.

Integer overflow in player.c in libwmf 0.2.8.4, as used in multiple products including (1) wv, (2) abiword, (3) freetype, (4) gimp, (5) libgsf, and (6) imagemagick allows remote attackers to execute arbitrary code via the MaxRecordSize header field in a WMF file.

wvWare wv through 1.2.9 contains a stack-based out-of-bounds read vulnerability in wvGetPAPXFKP and wvGetCHPXFKP caused by an unvalidated FKP run count. Attackers can supply a crafted .doc file with a large crun value to read kilobytes past the 512-byte stack buffer, crashing applications like AbiWord.

wvWare wv through 1.2.9 contains a heap-based out-of-bounds read vulnerability in wvGetSTSH in stylesheet.c that allows attackers to crash applications by supplying crafted Word stylesheets. Attackers can provide a .doc file with ten or fewer styles or out-of-range style base indexes to read past heap arrays, crashing applications such as AbiWord.

A heap buffer overflow flaw was found in the way the libwmf library processed WMF files containing BMP images. A specially crafted WMF file could cause an application using libwmf to crash or, possibly, execute arbitrary code.

Heap-based buffer overflow in the DecodeImage function in libwmf 0.2.8.4 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted "run-length count" in an image in a WMF file.

Integer overflow in wv2 before 0.2.3 might allow context-dependent attackers to execute arbitrary code via a crafted Microsoft Word document.

A memory allocation failure in function wmfmalloc in api.c was reported in libwmf. Opening a maliciously crafted file could cause the application to crash.

Multiple integer overflows in the WV library in wvWare (formerly mswordview) before 1.2.3, as used by AbiWord, KWord, and possibly other products, allow user-assisted remote attackers to execute arbitrary code via a crafted Microsoft Word (DOC) file that produces (1) large LFO clfolvl values in the wvGetLFOrecords function or (2) a large LFO nolfo value in the wvGetFLOPLF function.

meta.h in libwmf 0.2.8.4 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted WMF file.

Use-after-free vulnerability in libwmf 0.2.8.4 allows remote attackers to cause a denial of service (crash) via a crafted WMF file to the (1) wmf2gd or (2) wmf2eps command.
