Quick assessment

Affected
icculus PhysicsFS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PhysicsFS 3.2.0 及更早版本中存在一个越界读取漏洞，位于 函数中。攻击者可以通过在六字节 UTF-8 序列上因光标偏移一个字节而导致的错误，读取到名称缓冲区之后的数据。攻击者可以构造一个包含以六字节 UTF-8 序列结尾的条目名称的恶意归档文件，从而引发 函数和哈希计算过程中的越界读取，最终导致应用程序崩溃。

PhysicsFS through 3.2.0 Out-of-Bounds Read via __PHYSFS_utf8codepoint
Source: CVE Program / CVE List V5
Vulnerability Description
PhysicsFS through 3.2.0 contains an out-of-bounds read vulnerability in __PHYSFS_utf8codepoint() that allows attackers to read past name buffers via an off-by-one cursor advance on six-octet UTF-8 sequences. Attackers can supply a crafted archive with entry names ending in six-octet sequences, causing PHYSFS_utf8stricmp() and hashing to over-read and crash the application.
