FontForge SFD File Parsing Improper Validation of Array Index Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of FontForge. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of SFD files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated array. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-28563.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0108 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-15279:
    FontForge GUtils BMP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This     vulnerability allows remote attackers to execute arbitrary code on affected installations of FontForge.
    User interaction is required to exploit this vulnerability in that the target must visit a malicious page     or open a malicious file.

    The specific flaw exists within the parsing of pixels within BMP files. The issue results from the lack of     proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An     attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-     CAN-27517.

    CVE-2025-15269:
    FontForge SFD File Parsing Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows     remote attackers to execute arbitrary code on affected installations of FontForge. User interaction is     required to exploit this vulnerability in that the target must visit a malicious page or open a malicious     file.

    The specific flaw exists within the parsing of SFD files. The issue results from the lack of validating     the existence of an object prior to performing operations on the object. An attacker can leverage this     vulnerability to execute code in the context of the current user. Was ZDI-CAN-28564.
