Buffer overflow in the HPDF_Page_Circle function in hpdf_page_operator.c in Takeshi Kanno Haru Free PDF Library (libharu2, aka libharu) 2.0.7 and earlier allows context-dependent attackers to cause a denial of service (application crash) via certain arguments that yield a large amount of PDF data, as demonstrated by a filled circle.

Security readout for executives and security teams

This old vulnerability can crash software that uses Haru Free PDF Library to generate PDFs. The issue is triggered through specific circle-drawing arguments that create excessive PDF output. The public record describes denial of service, not data theft or code execution. Exposure is likely limited to applications or services that embed libharu 2.0.7 or earlier and allow user-influenced PDF drawing operations. Products are not enumerated in the source bundle, so affected downstream software must be inventoried locally. Treat this as a targeted availability risk for legacy PDF-generation components. It is not broadly urgent unless business-critical systems still use libharu 2.0.7 or earlier with user-driven PDF content. Mitigation focus: Inventory applications and build dependencies for libharu or libharu2 usage.; Identify any deployed libharu version at or below 2.0.7.; Check project tracker and release notes for vendor-confirmed fixed versions..
