    Package : nspr
    CVE ID : CVE-2016-1951
    Debian Bug : 583651

    Two vulnerabilities were reported in NSPR, a library to abstract over
    operating system interfaces developed by the Mozilla project.

    CVE-2016-1951

    q1 reported that the NSPR implementation of sprintf-style string
    formatting function miscomputed memory allocation sizes,
    potentially leading to heap-based buffer overflows

    The second issue concerns environment variable processing in NSPR.
    The library did not ignore environment variables used to configuring
    logging and tracing in processes which underwent a SUID/SGID/AT_SECURE transition at process start. In certain system configurations, this
    allowed local users to escalate their privileges.

    In addition, this nspr update contains further stability and
    correctness fixes and contains support code for an upcoming nss
    update.

    For the stable distribution (jessie), these problems have been fixed
    in version 2:4.12-1+debu8u1.

    For the unstable distribution (sid), these problems have been fixed in
    version 2:4.12-1.

    We recommend that you upgrade your nspr packages.
