| CVE-2020-6080 | 2 Debian, Videolabs | 2 Debian Linux, Libmicrodns | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An exploitable denial-of-service vulnerability exists in the resource allocation handling of Videolabs libmicrodns 0.1.0. When encountering errors while parsing mDNS messages, some allocated data is not freed, possibly leading to a denial-of-service condition via resource exhaustion. An attacker can send one mDNS message repeatedly to trigger this vulnerability through the function rr_read_RR [5] reads the current resource record, except for the RDATA section. This is read by the loop at in rr_read. For each RR type, a different function is called. When the RR type is 0x10, the function rr_read_TXT is called at [6]. | |||||
| CVE-2020-6079 | 2 Debian, Videolabs | 2 Debian Linux, Libmicrodns | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An exploitable denial-of-service vulnerability exists in the resource allocation handling of Videolabs libmicrodns 0.1.0. When encountering errors while parsing mDNS messages, some allocated data is not freed, possibly leading to a denial-of-service condition via resource exhaustion. An attacker can send one mDNS message repeatedly to trigger this vulnerability through decoding of the domain name performed by rr_decode. | |||||
| CVE-2020-6078 | 2 Debian, Videolabs | 2 Debian Linux, Libmicrodns | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages in mdns_recv, the return value of the mdns_read_header function is not checked, leading to an uninitialized variable usage that eventually results in a null pointer dereference, leading to service crash. An attacker can send a series of mDNS messages to trigger this vulnerability. | |||||
| CVE-2020-6077 | 2 Debian, Videolabs | 2 Debian Linux, Libmicrodns | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages, the implementation does not properly keep track of the available data in the message, possibly leading to an out-of-bounds read that would result in a denial of service. An attacker can send an mDNS message to trigger this vulnerability. | |||||
| CVE-2020-6073 | 2 Debian, Videolabs | 2 Debian Linux, Libmicrodns | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An exploitable denial-of-service vulnerability exists in the TXT record-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing the RDATA section in a TXT record in mDNS messages, multiple integer overflows can be triggered, leading to a denial of service. An attacker can send an mDNS message to trigger this vulnerability. | |||||
| CVE-2020-6072 | 2 Debian, Videolabs | 2 Debian Linux, Libmicrodns | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| An exploitable code execution vulnerability exists in the label-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing compressed labels in mDNS messages, the rr_decode function's return value is not checked, leading to a double free that could be exploited to execute arbitrary code. An attacker can send an mDNS message to trigger this vulnerability. | |||||
| CVE-2020-6071 | 2 Debian, Videolabs | 2 Debian Linux, Libmicrodns | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An exploitable denial-of-service vulnerability exists in the resource record-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing compressed labels in mDNS messages, the compression pointer is followed without checking for recursion, leading to a denial of service. An attacker can send an mDNS message to trigger this vulnerability. | |||||
