17 May 2021
Several security issues were fixed in DjVuLibre.
Releases
Packages
- djvulibre - DjVu image format library and tools
Details
It was discovered that DjVuLibre incorrectly handled certain memory
operations. If a user or automated system were tricked into processing a
specially crafted DjVu file, a remote attacker could cause applications
to hang or crash, resulting in a denial of service, or possibly execute
arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 21.04
Ubuntu 20.10
Ubuntu 20.04
Ubuntu 18.04
After a standard system update you need to reboot your computer to make
all the necessary changes.
