HIGH 8.8DOWNGRADE

CVE-2025-52930 is a high-severity flaw (CVSS 8.8) affecting sail. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A memory corruption vulnerability exists in the BMPv3 RLE Decoding functionality of the SAIL Image Decoding Library v0.9.8. When decompressing the image data from a specially crafted .bmp file, a heap-based buffer overflow can occur which allows for remote code execution. An attacker will need to convince the library to read a file to trigger this vulnerability.

sail sail DOWNGRADE

Affected: 0.9.8

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.9.8

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.9.8 (Debian / Ubuntu)

apt-cache madison sail sudo apt install sail=<VERSION_BEFORE_0.9.8> sudo apt-mark hold sail

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

dnf --showduplicates list sail sudo dnf downgrade sail-<VERSION_BEFORE_0.9.8> sudo dnf versionlock add sail

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.
