More information:

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.
