Related Vulnerabilities: CVE-2009-5029   CVE-2011-4609  

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the glibc library read timezone files. If a carefully-crafted timezone file was loaded by an application linked against glibc, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2009-5029) A denial of service flaw was found in the remote procedure call (RPC) implementation in glibc. A remote attacker able to open a large number of connections to an RPC service that is using the RPC implementation from glibc, could use this flaw to make that service use an excessive amount of CPU time. (CVE-2011-4609)
