MEDIUM 6.8MITIGATEMITIGATEDOWNGRADE

CVE-2012-4405 is a medium-severity flaw (CVSS 6.8) affecting cms, icclib, ghostscript. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Multiple integer underflows in the icmLut_allocate function in International Color Consortium (ICC) Format library (icclib), as used in Ghostscript 9.06 and Argyll Color Management System, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted (1) PostScript or (2) PDF file with embedded images, which triggers a heap-based buffer overflow. NOTE: this issue is also described as an array index

Why this priority

EPSS top 6%: very likely to be exploited

1. Check installed version

apt-cache policy ghostscript || rpm -q ghostscript || ghostscript --version

2. No fixed release: DOWNGRADE to a release before 9.06 (Debian / Ubuntu)

apt-cache madison ghostscript sudo apt install ghostscript=<VERSION_BEFORE_9.06> sudo apt-mark hold ghostscript

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list ghostscript sudo dnf downgrade ghostscript-<VERSION_BEFORE_9.06> sudo dnf versionlock add ghostscript

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
