"polkit was updated to the 0.113 release, fixing security issues and
bugs.

Security issues fixed :

  - Fixes CVE-2015-4625, a local privilege escalation due to
    predictable authentication session cookie values. Thanks
    to Tavis Ormandy, Google Project Zero for reporting this
    issue. For the future, authentication agents are
    encouraged to use PolkitAgentSession instead of using
    the D-Bus agent response API directly. (bsc#935119)

  - Fixes CVE-2015-3256, various memory corruption
    vulnerabilities in use of the JavaScript interpreter,
    possibly leading to local privilege escalation.
    (bsc#943816)

  - Fixes CVE-2015-3255, a memory corruption vulnerability
    in handling duplicate action IDs, possibly leading to
    local privilege escalation. Thanks to Laurent Bigonville
    for reporting this issue. (bsc#939246)

  - Fixes CVE-2015-3218, which allowed any local user to
    crash polkitd. Thanks to Tavis Ormandy, Google Project
    Zero, for reporting this issue. (bsc#933922)

Other issues fixed :

  - On systemd-213 and later, the 'active' state is shared
    across all sessions of an user, instead of being tracked
    separately.

  - pkexec, when not given a program to execute, runs the
    users shell by default.

  - Fixed shutdown problems on powerpc64le (bsc#950114)

  - polkit had a memory leak (bsc#912889)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

vulnerabilities :

  - A flaw was found in polkit before version 0.116. The
    implementation of the
    polkit_backend_interactive_authority_check_authorizatio
    n function in polkitd allows to test for authentication
    and trigger authentication of unrelated processes owned
    by other users. This may result in a local DoS and
    information disclosure.(CVE-2018-1116)

  - The polkit_backend_action_pool_init function in
    polkitbackend/polkitbackendactionpool.c in PolicyKit
    (aka polkit) before 0.113 might allow local users to
    gain privileges via duplicate action IDs in action
    descriptions.(CVE-2015-3255)

  - The authentication_agent_new function in
    polkitbackend/polkitbackendinteractiveauthority.c in
    PolicyKit (aka polkit) before 0.113 allows local users
    to cause a denial of service (NULL pointer dereference
    and polkitd daemon crash) by calling
    RegisterAuthenticationAgent with an invalid object
    path.(CVE-2015-3218)

  - A flaw was found in PolicyKit (aka polkit) 0.115 that
    allows a user with a uid greater than INT_MAX to
    successfully execute any systemctl
    command.(CVE-2018-19788)

  - Integer overflow in the authentication_agent_new_cookie
    function in PolicyKit (aka polkit) before 0.113 allows
    local users to gain privileges by creating a large
    number of connections, which triggers the issuance of a
    duplicate cookie value.(CVE-2015-4625)

bugs.

Security issues fixed :

  - Fixes CVE-2015-4625, a local privilege escalation due to
    predictable authentication session cookie values. Thanks
    to Tavis Ormandy, Google Project Zero for reporting this
    issue. For the future, authentication agents are
    encouraged to use PolkitAgentSession instead of using
    the D-Bus agent response API directly. (bsc#935119)

  - Fixes CVE-2015-3256, various memory corruption
    vulnerabilities in use of the JavaScript interpreter,
    possibly leading to local privilege escalation.
    (bsc#943816)

  - Fixes CVE-2015-3255, a memory corruption vulnerability
    in handling duplicate action IDs, possibly leading to
    local privilege escalation. Thanks to Laurent Bigonville
    for reporting this issue. (bsc#939246)

  - Fixes CVE-2015-3218, which allowed any local user to
    crash polkitd. Thanks to Tavis Ormandy, Google Project
    Zero, for reporting this issue. (bsc#933922)

Other issues fixed :

  - On systemd-213 and later, the 'active' state is shared
    across all sessions of an user, instead of being tracked
    separately.

  - pkexec, when not given a program to execute, runs the
    users shell by default.

  - Fixed shutdown problems on powerpc64le (bsc#950114)

  - polkit had a memory leak (bsc#912889)"

    (aka polkit) before 0.113 might allow local users to
    gain privileges via duplicate action IDs in action

  - The authentication_agent_new function in

    PolicyKit (aka polkit) before 0.113 allows local users
    to cause a denial of service (NULL pointer dereference
    and polkitd daemon crash) by calling
    RegisterAuthenticationAgent with an invalid object
    path.(CVE-2015-3218)

  - A flaw was found in PolicyKit (aka polkit) 0.115 that
    allows a user with a uid greater than INT_MAX to
    successfully execute any systemctl
    command.(CVE-2018-19788)

  - A flaw was found in polkit before version 0.116. The
    implementation of the
    polkit_backend_interactive_authority_check_authorizatio
    n function in polkitd allows to test for authentication
    and trigger authentication of unrelated processes owned
    by other users. This may result in a local DoS and
    information disclosure.(CVE-2018-1116)

  - Integer overflow in the authentication_agent_new_cookie
    function in PolicyKit (aka polkit) before 0.113 allows
    local users to gain privileges by creating a large
    number of connections, which triggers the issuance of a
    duplicate cookie value.(CVE-2015-4625)

    (aka polkit) before 0.113 might allow local users to
    gain privileges via duplicate action IDs in action
    descriptions.(CVE-2015-3255)

  - A NULL-pointer dereference flaw was discovered in
    polkitd. A malicious, local user could exploit this
    flaw to crash polkitd.(CVE-2015-3218)

  - A flaw was found in PolicyKit (aka polkit) 0.115 that
    allows a user with a uid greater than INT_MAX to
    successfully execute any systemctl
    command.(CVE-2018-19788)

  - It was found that Polkit's CheckAuthorization and
    RegisterAuthenticationAgent D-Bus calls did not
    validate the client provided UID. A specially crafted
    program could use this flaw to submit arbitrary UIDs,
    triggering various denial of service or minor
    disclosures, such as which authentication is cached in
    the victim's session.(CVE-2018-1116)

  - Integer overflow in the authentication_agent_new_cookie
    function in PolicyKit (aka polkit) before 0.113 allows
    local users to gain privileges by creating a large
    number of connections, which triggers the issuance of a
    duplicate cookie value.(CVE-2015-4625)

"According to the versions of the polkit packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - A flaw was found in polkit before version 0.116. The
    implementation of the
    polkit_backend_interactive_authority_check_authorizatio
    n function in polkitd allows to test for authentication
    and trigger authentication of unrelated processes owned
    by other users. This may result in a local DoS and
    information disclosure.(CVE-2018-1116)

  - Integer overflow in the authentication_agent_new_cookie
    function in PolicyKit (aka polkit) before 0.113 allows
    local users to gain privileges by creating a large
    number of connections, which triggers the issuance of a
    duplicate cookie value.(CVE-2015-4625)

  - The authentication_agent_new function in
    polkitbackend/polkitbackendinteractiveauthority.c in
    PolicyKit (aka polkit) before 0.113 allows local users
    to cause a denial of service (NULL pointer dereference
    and polkitd daemon crash) by calling
    RegisterAuthenticationAgent with an invalid object
    path.(CVE-2015-3218)

  - The polkit_backend_action_pool_init function in
    polkitbackend/polkitbackendactionpool.c in PolicyKit
    (aka polkit) before 0.113 might allow local users to
    gain privileges via duplicate action IDs in action
    descriptions.(CVE-2015-3255)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
