Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2016-7122)
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)
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)
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)
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)
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)
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)
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.
