Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2018-25009)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the WebPMuxCreateInternal() function in libwebp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
2) Out-of-bounds read (CVE-ID: CVE-2018-25010)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the ApplyFilter() function in libwebp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
3) Heap-based buffer overflow (CVE-ID: CVE-2018-25011)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in PutLE16() function in libwebp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger 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.
4) Out-of-bounds read (CVE-ID: CVE-2018-25012)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the WebPMuxCreateInternal() function in libwebp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
5) Out-of-bounds read (CVE-ID: CVE-2018-25013)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the ShiftBytes() function in libwebp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
6) Use-after-free (CVE-ID: CVE-2020-36329)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in libwebp. A remote attacker can trick the victim to open a specially crafted file, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
7) Out-of-bounds read (CVE-ID: CVE-2020-36330)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the ChunkVerifyAndAssign() function in libwebp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
8) Out-of-bounds read (CVE-ID: CVE-2020-36331)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the ChunkAssignData() function in libwebp. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
9) Resource exhaustion (CVE-ID: CVE-2020-36332)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in libwebp. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
