</package> + </affected> + <background> + <p> + The Linux kernel is responsible for managing the core aspects of a + GNU/Linux system, providing an interface for core system applications + as well as providing the essential structure and capability to access + hardware that is needed for a running system. + </p> + </background> + <description> + <p> + The Linux kernel allows a local attacker to obtain sensitive kernel + information by gaining access to kernel memory via several leaks in the + /proc interfaces. These vulnerabilities exist in various drivers which + make up a working Linux kernel, some of which are present across all + architectures and configurations. + </p> + <p> + CAN-2004-0415 deals with addressing invalid 32 to 64 bit conversions in + the kernel, as well as insecure direct access to file offset pointers + in kernel code which can be modified by the open(...), lseek(...) and + other core system I/O functions by an attacker. + </p> + <p> + CAN-2004-0685 deals with certain USB drivers using uninitialized + structures and then using the copy_to_user(...) kernel call to copy + these structures. This may leak uninitialized kernel memory, which can + contain sensitive information from user applications. + </p> + <p> + Finally, a race condition with the /proc/.../cmdline node was found, + allowing environment variables to be read while the process was still + spawning. If the race is won, environment variables of the process, + which might not be owned by the attacker, can be read. + </p> + </description> + <impact type="normal"> + <p> + These vulnerabilities allow a local unprivileged attacker to access + segments of kernel memory or environment variables which may contain + sensitive information. Kernel memory may contain passwords, data + transferred between processes and any memory which applications did not + clear upon exiting as well as the kernel cache and kernel buffers. + </p> + <p> + This information may be used to read sensitive data, open other attack + vectors for further exploitation or cause a Denial of Service if the + attacker can gain superuser access via the leaked information. + </p> + </impact> + <workaround> + <p> + There is no temporary workaround for any of these information leaks + other than totally disabling /proc support - otherwise, a kernel + upgrade is required. A list of unaffected kernels is provided along + with this announcement. + </p> + </workaround> + <resolution> + <p> + Users are encouraged to upgrade to the latest available sources for + their system: + </p> + <code> + # emerge sync + # emerge -pv your-favorite-sources + # emerge your-favorite-sources + + # # Follow usual procedure for compiling and installing a kernel. + # # If you use genkernel, run genkernel as you would normally.</code> + </resolution> + <references> + <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0415">CAN-2004-0415</uri> + <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0685">CAN-2004-0685</uri> + <uri link="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-1058">CVE-2004-1058</uri> + </references> + <metadata tag="submitter" timestamp="2004-08-17T02:16:55Z"> + plasmaroo + </metadata> +</glsa> |
