Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
EUVDB-ID: #VU28798
Risk: Medium
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2019-20421
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the Jp2Image::readMetadata() in jp2image.cpp. A remote attacker can create a specially crafted image file, pass it to the affected application and consume all available system resources or cause denial of service conditions.
MitigationUpdate exiv2 package to version 0.25-4+deb10u2.
Vulnerable software versionsexiv2 (Debian package): 0.6.2-1 - 0.27.3-3
CPE2.3https://www.debian.org/security/2021/dsa-4958
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU55919
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2021-3482
CWE-ID: N/A
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing EXIF data in Jp2Image::readMetadata() in jp2image.cpp. A remote attacker can create a specially crafted EXIF document, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate exiv2 package to version 0.25-4+deb10u2.
Vulnerable software versionsexiv2 (Debian package): 0.6.2-1 - 0.27.3-3

EUVDB-ID: #VU55920
Risk: Medium
CVSSv4.0: 4.8 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-29457
CWE-ID: N/A
Exploit availability: No
DescriptionThe 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`.
MitigationUpdate exiv2 package to version 0.25-4+deb10u2.

EUVDB-ID: #VU55921
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-29473
CWE-ID: N/A
Exploit availability: No
DescriptionThe 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.
MitigationUpdate exiv2 package to version 0.25-4+deb10u2.

EUVDB-ID: #VU55922
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2021-31292
CWE-ID: N/A
Exploit availability: No
DescriptionThe 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.
Update exiv2 package to version 0.25-4+deb10u2.
