Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Reachable Assertion (CVE-ID: CVE-2021-32815)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion when handling metadata of image files. A remote attacker can pass a specially crafted image to the application and perform a denial of service (DoS) attack.
2) Infinite loop (CVE-ID: CVE-2021-34334)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when processing metadata of image files. A remote attacker can pass a specially crafted image to the application, consume all available system resources and cause denial of service conditions.
3) Out-of-bounds read (CVE-ID: CVE-2021-37620)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition when processing metadata of a crafted image file. A remote attacker can pass a specially crafted image file to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.
4) Infinite loop (CVE-ID: CVE-2021-37622)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in JpegBase::printStructure(). A remote attacker can consume all available system resources and cause denial of service conditions.
5) Division by zero (CVE-ID: CVE-2021-34335)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to divide by zero error in Exiv2::Internal::resolveLens0xffff(). A remote attacker can pass specially crafted file to the application and crash it.
6) NULL pointer dereference (CVE-ID: CVE-2021-37615)
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 Exiv2::Internal::resolveLens0x319(). A remote attacker can pass specially crafted file to the application and perform a denial of service (DoS) attack.
7) NULL pointer dereference (CVE-ID: CVE-2021-37616)
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 Exiv2::Internal::resolveLens0x8ff(). A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
8) Out-of-bounds read (CVE-ID: CVE-2021-37618)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in Exiv2::Jp2Image::printStructure(). A remote attacker can pass a specially crafted file to the application, trigger an out-of-bounds read error and perform a denial of service attack.
9) Out-of-bounds read (CVE-ID: CVE-2021-37619)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
10) Infinite loop (CVE-ID: CVE-2021-37621)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in Image::printIFDStructure(). A remote attacker can consume all available system resources and cause denial of service conditions.
11) Infinite loop (CVE-ID: CVE-2021-37623)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in JpegBase::printStructure. A remote attacker can consume all available system resources and cause denial of service conditions.
