Bug ID: 16574
Summary: Memory leak in _nss_dns_gethostbyname4_r with big DNS
answer
Product: glibc
Version: 2.11
Status: NEW
Severity: normal
Priority: P2
Component: network
Assignee: unassigned at sourceware dot org
Reporter: schwab@linux-m68k.org
When resolving both IPv4 and IPv6 and the answers from the DNS server are too
big to fit together in the supplied buffer then a new buffer for the second
answer is allocated by send_vc / send_dg, but _nss_dns_gethostbyname4_r fails
to deallocate it. This is the only place where the resolver functions are
called in such a way that they may work with two buffers.
