Why it matters
Critical vulnerability requiring immediate validation against your environment.
Recommended admin actions
- Prioritize validation immediately due to critical CVSS severity.
Technical summary
fs_read_glyphs() in the libXfont2 font-server client (src/fc/fserve.c) indexes the per-character encoding[] array using num_chars from the FS_QueryXBitmaps16 reply, but that array was allocated with a size derived from num_extents in the separate FS_QueryXExtents16 reply. The two CARD32 fields are never cross-checked. A malicious or compromised font server can send a small num_extents (e.g. 1) in the extents reply, then a large num_chars (e.g. 100000) in the bitmaps reply. This causes attacker-controlled out-of-bounds heap read and writes.

About the Vulnerability Pulse CVE Feed
The Vulnerability Pulse feed tracks live CVE advisories sourced from the National Vulnerability Database and vendor security disclosures. It is designed for SOC analysts, IT administrators, and security teams who need a fast, filterable view of current vulnerabilities without digging through raw NVD data.
How to Use the CVE Advisory Tracker
Use the severity filters to narrow results to Critical or High priority vulnerabilities. Filter by vendor to focus on software and hardware relevant to your environment. Export to CSV for reporting, ticketing, or patch prioritization workflows.
What Is a CVE Advisory?
A CVE (Common Vulnerabilities and Exposures) advisory is a public disclosure of a security vulnerability assigned a unique identifier by MITRE. Advisories include severity scores (CVSS), affected versions, and remediation guidance. Monitoring CVE advisories is a core function of vulnerability management programs and SOC operations.
CVE Analysis & Writeups
For in-depth analysis of specific vulnerabilities, visit the IT Knowledge Bases blog for CVE breakdowns, exploitation analysis, and remediation guidance written for security practitioners.
