Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2018-20097)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
There is a SEGV in Exiv2::Internal::TiffParserWorker::findPrimaryGroups of tiffimage_int.cpp in Exiv2 0.27-RC3. A crafted input will lead to a remote denial of service attack.
2) Resource management error (CVE-ID: CVE-2019-13112)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to memory allocation error in PngChunk::parseChunkContent() function. A remote attacker can create a specially crafted PNG image, pass it to the application and perform a denial of service attack.
3) Heap-based buffer overflow (CVE-ID: CVE-2021-29457)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can trick the victim top open a specially crafted image, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Note that this bug is only triggered when _writing_ the metadata, which is a less frequently used Exiv2 operation than _reading_ the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `insert`.
4) Out-of-bounds read (CVE-ID: CVE-2021-29473)
The vulnerability allows a remote attacker to gain access to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition when processing Exif, IPTC, XMP and ICC image metadata. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and crash the affected application.
5) 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.
6) 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.
7) 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.
8) 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.
