Detail
| Witold Baryluk discovered that MaraDNS, a simple security-focused Domain Name Service server, may overflow an internal buffer when handling requests with a large number of labels, causing a server crash and the consequent denial of service. For the oldstable distribution (lenny), this problem has been fixed in version 1.3.07.09-2.1. For the stable distribution (squeeze) and greater this problem had already been fixed in version 1.4.03-1.1. We recommend that you upgrade your maradns packages. |

| 70630 | MaraDNS dns/Compress.c compress_add_dlabel_points() Function Remote Overflow DoS MaraDNS is prone to an overflow condition. The 'compress_add_dlabel_points()' function in 'dns/Compress.c' fails to properly sanitize user-supplied input resulting in a heap-based buffer overflow. With a specially crafted request, a remote attacker can potentially cause a denial of service. |
