Off-by-one error in the bzinflate function in Bzip2.xs in the Compress-Raw- Bzip2 module before 2.018 for Perl allows context-dependent attackers to cause a denial of service (application hang or crash) via a crafted bzip2 compressed stream that triggers a buffer overflow, a related issue to CVE-2009-1391.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
