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.
