t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, reads from invalid memory locations, which allows remote attackers to cause a denial of service (application crash) via a crafted Type 1 font in a PDF document, a different vulnerability than CVE-2011-0764.

Security readout for executives and security teams

CVE-2011-1552 is an older PDF/font parsing flaw. A malicious PDF containing a crafted Type 1 font can crash affected applications that use vulnerable t1lib code, including older Xpdf and teTeX-related deployments. The public record supports denial of service, not confirmed active exploitation or a named data-theft impact. Exposure is most likely on legacy systems that still process untrusted PDFs or Type 1 fonts using t1lib 5.1.2 or earlier, Xpdf before 3.02pl6, teTeX, or downstream distribution packages referenced by Red Hat, Mandriva, and Gentoo advisories. Prioritize remediation where legacy PDF processing is exposed to external files, customer uploads, or email attachments. This is mainly an availability risk, but crashes in document-processing services can disrupt business workflows and may indicate broader legacy dependency debt. Mitigation focus: Inventory systems using t1lib, Xpdf, teTeX, or PDF conversion workflows.; Update affected packages using vendor or distribution advisories.; Verify Xpdf deployments are not older than 3.02pl6..
