CVE-2011-1779
Multiple use-after-free vulnerabilities in libarchive 2.8.4 and 2.8.5 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted (1) TAR archive or (2) ISO9660 image.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
