CVE-2024-12084

CVE-2024-12084 在 rsync 守护进程中发现了基于堆的缓冲区溢出缺陷。该问题是由于代码中错误处理了由攻击者控制的校验和长度（s2length）所致。当 MAXDIGESTLEN 超过固定的 SUMLENGTH（16 字节）时，攻击者可以在 sum2 缓冲区中越界写入。 这种检测方法是如何工作的？ 该模板匹配 rsync 协议版本 31，该版本很可能受到 CVE-2024-12084 的影响。在 rsync 中，我们可以通过将协议映射到版本来确定这一点。 root@kitploit: vulnerable: = 3.2.7 - protocol 31 unaffected:...

rsync: Heap Buffer Overflow in Rsync due to Improper Checksum Length Handling

A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths s2length in the code. When MAXDIGESTLEN exceeds the fixed SUMLENGTH 16 bytes, an attacker can write out of bounds in the sum2 buffer...

Rsync 安全漏洞

Rsync is a fast and versatile file copying tool open-sourced by RsyncProject. It is used for remote files and local files. A security vulnerability exists in Rsync versions prior to 3.4, which stems from the presence of a heap-based buffer overflow that allows an attacker to write out-of-bounds...
