Synopsis
Multiple vulnerabilities were found in glibc, the worst of which allowing local attackers to execute arbitrary code as root.Background
The GNU C library is the standard C library used by Gentoo Linux systems.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| sys-libs/glibc | < 2.11.2-r3 | >= 2.11.2-r3 | All supported architectures |
Description
Multiple vulnerabilities were found in glibc, amongst others the widely-known recent LD_AUDIT and $ORIGIN issues. For further information please consult the CVE entries referenced below.
Impact
A local attacker could execute arbitrary code as root, cause a Denial of Service, or gain privileges. Additionally, a user-assisted remote attacker could cause the execution of arbitrary code, and a context-dependent attacker could cause a Denial of Service.
Workaround
There is no known workaround at this time.
Resolution
All GNU C library users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-libs/glibc-2.11.2-r3"
