An invalid memory address dereference was discovered in getString in util/decompile.c in libming 0.4.8 for CONSTANT16 data. The vulnerability causes a segmentation fault and application crash, which leads to denial of service.

Fixes: CVE-2018-6358, CVE-2018-7867, CVE-2018-7868, CVE-2018-7870, CVE-2018-7871, CVE-2018-7872, CVE-2018-7875, CVE-2018-9165.

Multiple vulnerabilities have been discovered in Ming :

CVE-2018-6358

Heap-based buffer overflow vulnerability in the printDefineFont2 function (util/listfdb.c). Remote attackers might leverage this vulnerability to cause a denial of service via a crafted swf file.

CVE-2018-7867

Heap-based buffer overflow vulnerability in the getString function (util/decompile.c) during a RegisterNumber sprintf. Remote attackers might leverage this vulnerability to cause a denial of service via a crafted swf file.

CVE-2018-7868

Heap-based buffer over-read vulnerability in the getName function (util/decompile.c) for CONSTANT8 data. Remote attackers might leverage this vulnerability to cause a denial of service via a crafted swf file.

CVE-2018-7870

Invalid memory address dereference in the getString function (util/decompile.c) for CONSTANT16 data. Remote attackers might leverage this vulnerability to cause a denial of service via a crafted swf file.

CVE-2018-7871

Heap-based buffer over-read vulnerability in the getName function (util/decompile.c) for CONSTANT16 data. Remote attackers might leverage this vulnerability to cause a denial of service via a crafted swf file.

CVE-2018-7872

Invalid memory address dereference in the getName function (util/decompile.c) for CONSTANT16 data. Remote attackers might leverage this vulnerability to cause a denial of service via a crafted swf file.

CVE-2018-7875

Heap-based buffer over-read vulnerability in the getName function (util/decompile.c) for CONSTANT8 data. Remote attackers might leverage this vulnerability to cause a denial of service via a crafted swf file.

CVE-2018-9165

The pushdup function (util/decompile.c) performs shallow copy of String elements (instead of deep copy), allowing simultaneous change of multiple elements of the stack, which indirectly makes the library vulnerable to a NULL pointer dereference in getName (util/decompile.c). Remote attackers might leverage this vulnerability to cause dos via a crafted swf file.

For Debian 7 'Wheezy', these problems have been fixed in version 0.4.4-1.1+deb7u8.

We recommend that you upgrade your ming packages.
