CVSS v3.1
Official Description
Off-by-one error in t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory read, integer overflow, and invalid pointer dereference, a different vulnerability than CVE-2011-0764.
Technical Analysis
CVE-2011-1554 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
