Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2020-20891)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the config_input() function in libavfilter/vf_gblur.c in FFmpeg. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
2) Division by zero (CVE-ID: CVE-2020-20892)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a division by zero error within the filter_frame() function in libavfilter/vf_lenscorrection.c in FFmpeg. A remote attacker can pass specially crafted data to the application and crash it.
3) NULL pointer dereference (CVE-ID: CVE-2020-20896)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the latm_write_packet() function in libavformat/latmenc.c in FFmpeg. A remote attacker can perform a denial of service (DoS) attack.
4) Out-of-bounds read (CVE-ID: CVE-2020-20902)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the long_term_filter() function in g729postfilter.c in FFmpeg. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.
5) Buffer overflow (CVE-ID: CVE-2020-22028)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the ilter_vertically_8() function in libavfilter/vf_avgblur.c in FFmpeg. A remote attacker can trigger memory corruption and crash the application.
6) Heap-based buffer overflow (CVE-ID: CVE-2020-22036)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the filter_intra() function at libavfilter/vf_bwdif.c in FFmpeg. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
7) Memory leak (CVE-ID: CVE-2020-22037)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within avcodec_alloc_context3() function in options.c in FFmpeg. A remote attacker can perform a denial of service attack.
8) Memory leak (CVE-ID: CVE-2020-22042)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within the link_filter_inouts() function in libavfilter/graphparser.c. A remote attacker can perform a denial of service attack.
9) Out-of-bounds write (CVE-ID: CVE-2020-35965)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the decode_frame() function in libavcodec/exr.c. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
10) Input validation error (CVE-ID: CVE-2021-3566)
The vulnerability allows a remote attacker to manipulate data.
The vulnerability exists due to tty demuxer does not have a 'read_probe' function assigned to it. A remote attacker can create a legitimate "ffconcat" file that references an image, followed by a file
the triggers the tty demuxer, the contents of the second file will be
copied into the output file verbatim.
11) Integer overflow (CVE-ID: CVE-2021-38092)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the filter_prewitt() function in libavfilter/vf_convolution.c in FFmpeg . A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
12) Integer overflow (CVE-ID: CVE-2021-38093)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the filter_robert() function in libavfilter/vf_convolution.c in FFmpeg. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
13) Integer overflow (CVE-ID: CVE-2021-38094)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the filter_sobel() function in libavfilter/vf_convolution.c in Ffmpeg. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
14) NULL pointer dereference (CVE-ID: CVE-2022-3109)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the vp3_decode_frame() function in libavcodec/vp3.c in FFmpeg. A remote attacker can perform a denial of service (DoS) attack.
