--- title: "CVE-2013-4588\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2013-4588?format=md keywords: index, follow --- # CVE-2013-4588 Publication date 20 November 2013 Last updated 4 July 2026 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) ## Cvss 3 Severity Score **7.0 · High** [Score breakdown](https://ubuntu.com/security/CVE-2013-4588?format=md#impact-score) Toggle side navigation ## Description Multiple stack-based buffer overflows in net/netfilter/ipvs/ip\_vs\_ctl.c in the Linux kernel before 2.6.33, when CONFIG\_IP\_VS is used, allow local users to gain privileges by leveraging the CAP\_NET\_ADMIN capability for (1) a getsockopt system call, related to the do\_ip\_vs\_get\_ctl function, or (2) a setsockopt system call, related to the do\_ip\_vs\_set\_ctl function. A user/program with CAP\_NET\_ADMIN privileges could use this flaw to further escalate their privileges on a system. ### From the Ubuntu Security Team A flaw was discovered in the Linux kernel's IP Virtual Server (IP\_VS) support. A local user with the CAP\_NET\_ADMIN capability could exploit this flaw to gain additional administrative privileges.
