CVE-2018-4011

CUJO Smart Firewall mdnscap (firmware 7003) is affected by CVE-2018-4011: an integer underflow in SRV RDATA parsing during mDNS DNS RR processing leads to out-of-bounds heap access and a crash of the mdnscap process. The flaw arises when rdlength is small (e.g., 0x05) and the code subtracts 6 wit...

CVE-2018-4011

An exploitable integer underflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall, version 7003. When parsing SRV records in an mDNS packet, the "RDLENGTH" value is handled incorrectly, leading to an out-of-bounds access that crashes the mdnscap process. An unauthenticated...

CVE-2018-3985

An exploitable double free vulnerability exists in the mdnscap binary of the CUJO Smart Firewall. When parsing mDNS packets, a memory space is freed twice if an invalid query name is encountered, leading to arbitrary code execution in the context of the mdnscap process. An unauthenticated attacke...

CVE-2018-4003

The CVE-2018-4003 issue affects CUJO Smart Firewall (firmware 7003) in the mdnscap mDNS parser. A heap-based buffer overflow occurs when parsing string lengths in mDNS resource records, allowing an unauthenticated remote attacker to trigger arbitrary code execution in the mdnscap process; exploit...

CVE-2018-4003

An exploitable heap overflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall running firmware 7003. The string lengths are handled incorrectly when parsing character strings in mDNS resource records, leading to arbitrary code execution in the context of the mdnscap process. ...

CUJO Smart Firewall Denial of Service Vulnerability

CUJO Smart Firewall is a home smart firewall device from CUJO USA. A denial of service vulnerability exists in the mdnscap binary in the CUJO Smart Firewall using firmware version 7003, which stems from the program failing to securely handle compressed pointers when parsing labels in mDNS packets...

CUJO Smart Firewall mdnscap mDNS record parsing code execution vulnerability

Summary An exploitable double free vulnerability exists in the mdnscap binary of the CUJO Smart Firewall. When parsing mDNS packets, a memory space is freed twice if an invalid query name is encountered, leading to arbitrary code execution in the context of the mdnscap process. An unauthenticated...

CUJO Smart Firewall mdnscap mDNS label compression denial-of-service vulnerability

Summary An exploitable denial-of-service vulnerability exists in the mdnscap binary of the CUJO Smart Firewall running firmware 7003. When parsing labels in mDNS packets, the firewall unsafely handles label compression pointers, leading to an uncontrolled recursion that eventually exhausts the...

CUJO Smart Firewall mdnscap mDNS character-strings code execution vulnerability

Summary An exploitable heap overflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall running firmware 7003. The string lengths are handled incorrectly when parsing character strings in mDNS resource records, leading to arbitrary code execution in the context of the mdnscap...

CUJO Smart Firewall mdnscap mDNS SRV record denial-of-service vulnerability

Summary An exploitable integer underflow vulnerability exists in the mdnscap binary of the CUJO Smart Firewall, version 7003. When parsing SRV records in an mDNS packet, the “RDLENGTH” value is handled incorrectly, leading to an out-of-bounds access that crashes the mdnscap process. An...

Information disclosure

In tinysvcmdns through 2018-01-16, an mDNS server processing a crafted packet can perform arbitrary data read operations up to 16383 bytes from the start of the buffer. This can lead to a segmentation fault in uncompressnlabel in mdns.c and a crash of the server depending on the memory protection...

Design/Logic Flaw

In tinysvcmdns through 2018-01-16, a maliciously crafted mDNS Multicast DNS packet triggers an infinite loop while parsing an mDNS query. When mDNS compressed labels point to each other, the function uncompressnlabel goes into an infinite loop trying to analyze the packet with an mDNS query. As a...
