Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2019-13108)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in Exiv2 through 0.27.1 due to PngImage::readMetadata mishandles a zero value for iccOffset. A remote attacker can create a crafted PNG image file, trigger integer overflow and perform denial of service (DoS) attack.
2) Out-of-bounds read (CVE-ID: CVE-2019-13504)
The vulnerability allows a remote attacker to cause a denial of service (DoS) condition on a targeted system.
The vulnerability exists due to an out-of-bounds read error in the "Exiv2::MrwImage::readMetadata" function in the "mrwimage.cpp" file. A remote attacker can create a specially crafted media file, trick the victim into opening it and cause the affected application to crash.
3) 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.
4) 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.
5) 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.
6) 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.
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-2021-34334)
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.
9) 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.
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) 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.
12) 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.
13) 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.
14) Out-of-bounds read (CVE-ID: CVE-2021-37619)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
