Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2021-31291)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in jp2image.cpp in Exiv2. A remote attacker can use crafted metadata to 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.
2) Integer overflow (CVE-ID: CVE-2021-31292)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to integer overflow CrwMap::encode0x1810 of Exiv2. A remote attacker can pass specially crafted data to the application, trigger integer overflow and crash the application.
3) 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.
4) Out-of-bounds read (CVE-ID: CVE-2021-37619)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
5) 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.
6) 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.
7) 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.
8) 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.
9) 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.
10) 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.
11) 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.
12) 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.
13) 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.
