CVE-2007-3508

Name of the Vulnerable Software and Affected Versions: glibc versions prior to 2.5-rc4

Description: The issue is related to an integer overflow in the process envvars function in elf/rtld.c in glibc. This might allow local users to execute arbitrary code via a large LD HWCAP MASK environment variable value. However, the glibc maintainers do not believe that this issue is exploitable for code execution. The exploitation of this issue can lead to a violation of confidentiality, integrity, and availability of protected information and can be performed locally.

Recommendations: For glibc versions prior to 2.5-rc4, update to version 2.5-rc4 or later to resolve the issue. As a temporary workaround, consider restricting the use of the LD HWCAP MASK environment variable to minimize the risk of exploitation.
