Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2023-49502)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in ff_bwdif_filter_intra_c() function in the libavfilter/bwdifdsp.c. A remote attacker can pass specially crafted input to the application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Buffer overflow (CVE-ID: CVE-2023-50007)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the heav_samples_set_silence() function in thelibavutil/samplefmt.c. A remote attacker can pass specially crafted input to the application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Buffer overflow (CVE-ID: CVE-2023-50008)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in av_malloc() function in libavutil/mem.c. A remote attacker can pass specially crafted input to the application, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Heap-based buffer overflow (CVE-ID: CVE-2024-31582)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the raw_block_rectangle() function of libavfilter/vf_codecview.c.. 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.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Out-of-bounds read (CVE-ID: CVE-2024-35367)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in libavcodec/ppc/vp8dsp_altivec.c. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.
6) Double free (CVE-ID: CVE-2024-35368)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the rkmpp_retrieve_frame() function in libavcodec/rkmppdec.c. A remote attacker can pass specially crafted data to the application, trigger double free error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Out-of-bounds read (CVE-ID: CVE-2025-0518)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in libavfilter/af_pan.c. A remote attacker can pass specially crafted input to the application, trigger an out-of-bounds read error and read contents of memory on the system.
8) NULL pointer dereference (CVE-ID: CVE-2025-7700)
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 decode_init() function in the ALS audio decoder. A remote attacker can pass specially crafted image to the application and perform a denial of service (DoS) attack.
9) Reachable assertion (CVE-ID: CVE-2025-22919)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion within the init_audio() function in libavfilter/buffersrc.c. A remote attacker can pass a specially crafted AAC file to the application, trigger an assertion failure and perform a denial of service (DoS) attack.
