EUVDB-ID: #VU53321
Risk: High
CVSSv4.0: 5.7 [CVSS:4.0/AV:L/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-2021-32491
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within render() function in tools/ddjvu. A remote attacker can create a specially crafted djvu file, trick the victim into opening it, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected package djvulibre to the latest version.

EUVDB-ID: #VU53320
Risk: Medium
CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-32492
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in DJVU::DataPool::has_data() function. A remote attacker can create a specially crafted djvu file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
MitigationUpdate the affected package djvulibre to the latest version.
