The version of Google Chrome installed on the remote Windows host is prior to 46.0.2490.71. It is, therefore, affected by multiple vulnerabilities :

  - A same-origin bypass vulnerability exists in Blink that     allows an attacker to bypass the same-origin policy.
    (CVE-2015-6755)

  - A use-after-free error exists in PDFium. A remote     attacker can exploit this to dereference already freed     memory, potentially resulting in the execution of     arbitrary code or a denial of service condition.
    (CVE-2015-6756)

  - A use-after-free error exists in ServiceWorker. A remote     attacker can exploit this to dereference already freed     memory, potentially resulting in the execution of     arbitrary code. (CVE-2015-6757)

  - An unspecified bad cast issue exists in PDFium that a     remote attacker can exploit to have an unspecified     impact. (CVE-2015-6758)

  - An unspecified flaw exists in LocalStorage that allows     an attacker to disclose sensitive information.
    (CVE-2015-6759)

  - An unspecified flaw exists when handling errors that     allows an attacker to have an unspecified impact.
    (CVE-2015-6760)

  - A memory corruption issues exists in FFMpeg due to     improper validation of user-supplied input. A remote     attacker can exploit this to execute arbitrary code.
    (CVE-2015-6761)

  - An unspecified flaw exists when handling CSS fonts. An     attacker can exploit this to bypass cross-origin     resource sharing (CORS) restrictions. (CVE-2015-6762)

  - Multiple unspecified high severity issues exist that     allow an attacker to have an unspecified impact.
    (CVE-2015-6763)

NVD reports :

The update_dimensions function in libavcodec/vp8.c in FFmpeg through 2.8.1, as used in Google Chrome before 46.0.2490.71 and other products, relies on a coefficient-partition count during multi-threaded operation, which allows remote attackers to cause a denial of service (race condition and memory corruption) or possibly have unspecified other impact via a crafted WebM file.

The ljpeg_decode_yuv_scan function in libavcodec/mjpegdec.c in FFmpeg before 2.8.2 omits certain width and height checks, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted MJPEG data.

The ff_hevc_parse_sps function in libavcodec/hevc_ps.c in FFmpeg before 2.8.2 does not validate the Chroma Format Indicator, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted High Efficiency Video Coding (HEVC) data.

The decode_uncompressed function in libavcodec/faxcompr.c in FFmpeg before 2.8.2 does not validate uncompressed runs, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted CCITT FAX data.

The init_tile function in libavcodec/jpeg2000dec.c in FFmpeg before 2.8.2 does not enforce minimum-value and maximum-value constraints on tile coordinates, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted JPEG 2000 data.

The jpeg2000_read_main_headers function in libavcodec/jpeg2000dec.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not enforce uniqueness of the SIZ marker in a JPEG 2000 image, which allows remote attackers to cause a denial of service (out-of-bounds heap-memory access) or possibly have unspecified other impact via a crafted image with two or more of these markers.

Integer overflow in the ff_ivi_init_planes function in libavcodec/ivi.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 allows remote attackers to cause a denial of service (out-of-bounds heap-memory access) or possibly have unspecified other impact via crafted image dimensions in Indeo Video Interactive data.

The smka_decode_frame function in libavcodec/smacker.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not verify that the data size is consistent with the number of channels, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Smacker data.
