Vulnerability Title
dhcpcd Stack Out-of-Bounds Write in dhcp6_makemessage()
Vulnerability Description
dhcpcd through 10.3.2, fixed in commit 2f00c7b, contains a one-byte stack out-of-bounds write vulnerability in dhcp6_makemessage() in src/dhcp6.c that allows unauthenticated same-link attackers to write beyond a fixed local buffer by serializing an oversized RFC6603 OPTION_PD_EXCLUDE option body. Attackers can send a crafted DHCPv6 ADVERTISE message containing an IA_PD IAPREFIX /0 with a valid OPTION_PD_EXCLUDE using an exclude prefix length of /121 through /128 to trigger the out-of-bounds write and potentially corrupt adjacent stack memory.

Vulnerability Title
NetworkConfiguration dhcpcd 缓冲区错误漏洞
Vulnerability Description
NetworkConfiguration dhcpcd是NetworkConfiguration团队的一款DHCP客户端软件。 NetworkConfiguration dhcpcd 10.3.2及之前版本存在缓冲区错误漏洞,该漏洞源于src/dhcp6.c中的dhcp6_makemessage()函数存在单字节栈越界写入,未经身份验证的同链路攻击者可通过序列化过大的OPTION_PD_EXCLUDE选项体,写入固定本地缓冲区之外,从而触发越界写入并可能破坏相邻堆栈内存。
