HighCVSS 7.8
mspack/lzxd.c in libmspack 0.5alpha, as used in ClamAV 0.99.2, allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted CHM file.
-
MediumCVSS 5.5
The cabd_read_string function in mspack/cabd.c in libmspack 0.5alpha, as used in ClamAV 0.99.2 and other products, allows remote attackers to cause a denial of service (stack-based buffer over-read and application crash) via a crafted CAB file.
-
MediumCVSS 4.3
The cabd_extract function in cabd.c in libmspack before 0.5 does not properly maintain decompression callbacks in certain cases where an invalid file follows a valid file, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash)...
-
MediumCVSS 6.8
Off-by-one error in the READ_ENCINT macro in chmd.c in libmspack before 0.5 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted CHM file.
-
MediumCVSS 4.3
Off-by-one error in the lzxd_decompress function in lzxd.c in libmspack before 0.5 allows remote attackers to cause a denial of service (buffer under-read and application crash) via a crafted CAB archive.
-
MediumCVSS 4.3
Off-by-one error in the inflate function in mszipd.c in libmspack before 0.5 allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted CAB archive.
-
MediumCVSS 4.3
The chmd_read_headers function in chmd.c in libmspack before 0.5 does not validate name lengths, which allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted CHM file.
-
MediumCVSS 4.3
Multiple integer overflows in the search_chunk function in chmd.c in libmspack before 0.5 allow remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted CHM file.
-
MediumCVSS 4.3
The chmd_init_decomp function in chmd.c in libmspack before 0.5 does not properly validate the reset interval, which allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted CHM file.
-
MediumCVSS 5.0
Integer overflow in the qtmd_decompress function in libmspack 0.4 allows remote attackers to cause a denial of service (hang) via a crafted CAB file, which triggers an infinite loop.
