Description

This security bulletin contains information about 7 vulnerabilities.


1) Resource management error (CVE-ID: CVE-2016-7122)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.

The avi_read_nikon function in libavformat/avidec.c in FFmpeg before 3.1.4 is vulnerable to infinite loop when it decodes an AVI file that has a crafted 'nctg' structure.


2) Out-of-bounds read (CVE-ID: CVE-2016-7450)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to execute arbitrary code.

The ff_log2_16bit_c function in libavutil/intmath.h in FFmpeg before 3.1.4 is vulnerable to reading out-of-bounds memory when it decodes a malformed AIFF file.


3) Out-of-bounds read (CVE-ID: CVE-2016-7502)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to execute arbitrary code.

The cavs_idct8_add_c function in libavcodec/cavsdsp.c in FFmpeg before 3.1.4 is vulnerable to reading out-of-bounds memory when decoding with cavs_decode.


4) Information disclosure (CVE-ID: CVE-2016-7555)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to gain access to sensitive information.

The avi_read_header function in libavformat/avidec.c in FFmpeg before 3.1.4 is vulnerable to memory leak when decoding an AVI file that has a crafted "strh" structure.


5) Buffer overflow (CVE-ID: CVE-2016-7562)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.

The ff_draw_pc_font function in libavcodec/cga_data.c in FFmpeg before 3.1.4 allows remote attackers to cause a denial of service (buffer overflow) via a crafted AVI file.


6) Input validation error (CVE-ID: CVE-2016-7785)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.

The avi_read_seek function in libavformat/avidec.c in FFmpeg before 3.1.4 allows remote attackers to cause a denial of service (assert fault) via a crafted AVI file.


7) NULL pointer dereference (CVE-ID: CVE-2016-7905)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.

The read_gab2_sub function in libavformat/avidec.c in FFmpeg before 3.1.4 allows remote attackers to cause a denial of service (NULL pointer used) via a crafted AVI file.
