-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3251-2 security@xxxxxxxxxx http://www.debian.org/security/ Salvatore Bonaccorso May 07, 2015 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : dnsmasq Debian Bug : 784571 The update for dnsmasq issued as DSA-3251-1 introduced a regression for the armel and armhf builds causing dnsmasq failing to start under certain configurations. Updated packages are now available to address this regression. Additionally dnsmasq was patched to handle the case were the libc headers defined SO_REUSEPORT, but is not supported by the running kernel. For reference, the original advisory text follows. Nick Sampanis discovered that dnsmasq, a small caching DNS proxy and DHCP/TFTP server, did not properly check the return value of the setup_reply() function called during a TCP connection, which is used then as a size argument in a function which writes data on the client's connection. A remote attacker could exploit this issue via a specially crafted DNS request to cause dnsmasq to crash, or potentially to obtain sensitive information from process memory. For the oldstable distribution (wheezy), this problem has been fixed in version 2.62-3+deb7u3. We recommend that you upgrade your dnsmasq packages.
