Multiple heap-based buffer overflows in parser.c in libming 0.4.7 allow remote attackers to cause a denial of service (listswf application crash) or possibly have unspecified other impact via a crafted SWF file. NOTE: this issue exists because of an incomplete fix for CVE-2016-9831.

Release 0.4.8 (no ABI or API changes)

  - Add PHP7 compatibility

  - Fix C++ output of disassembler

  - Fix heap overflows in parser.c (CVE-2017-7578)

  - Avoid division by zero in listmp3 when no valid frame     was found (CVE-2016-9265)

  - Don't try printing unknown block (CVE-2016-9828)

  - Parse Protect tag's Password as string (CVE-2016-9827)

  - Check values before deriving malloc parameters from them     in parser.c (CVE-2016-9829)

  - Make readString() stop reading string past buffer's end

  - Return EOF when reading unsigned values hits end of     memory backed buffer

  - Exit immediately when unexpected EOF is by fgetc() in     utility programs (CVE-2016-9831)

  - Fix using EOF marker -1 value as a valid flag byte     (CVE-2016-9266)

  - Fix division by zero sample rate due to global buffer     overflow (CVE-2016-9264, CVE-2016-9265)

It was discovered that there were multiple heap-based buffer overflows in ming, a library to generate SWF (Flash) files.

The updated packages prevent a crash in the 'listswf' utility due to a heap-based buffer overflow in the parseSWF_RGBA function and several other functions in parser.c.

AddressSanitizer flagged them as invalid writes 'of size 1' but the heap could be written to multiple times. The overflows are caused by a pointer behind the bounds of a statically allocated array of structs of type SWF_GRADIENTRECORD.

For Debian 7 'Wheezy', this issue has been fixed in ming version 1:0.4.4-1.1+deb7u2.

We recommend that you upgrade your ming packages.
