Scientific Linux Security Update : X.org X11 libraries on SL7.x x86_64
High Nessus Plugin ID 102636
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionThe following packages have been upgraded to a later upstream version:
libX11 (1.6.5), libXaw (1.0.13), libXdmcp (1.1.2), libXfixes (5.0.3), libXfont (1.5.2), libXi (1.7.9), libXpm (3.5.12), libXrandr (1.5.1), libXrender (0.9.10), libXt (1.1.5), libXtst (1.2.3), libXv (1.0.11), libXvMC (1.0.10), libXxf86vm (1.1.4), libdrm (2.4.74), libepoxy (1.3.1), libevdev (1.5.6), libfontenc (1.1.3), libvdpau (1.1.1), libwacom (0.24), libxcb (1.12), libxkbfile (1.0.9), mesa (17.0.1), mesa-private-llvm (3.9.1), xcb-proto (1.12), xkeyboard-config (2.20), xorg-x11-proto-devel (7.7).
Security Fix(es) :
- An integer overflow flaw leading to a heap-based buffer overflow was found in libXpm. An attacker could use this flaw to crash an application using libXpm via a specially crafted XPM file. (CVE-2016-10164)
- It was discovered that libXdmcp used weak entropy to generate session keys. On a multi-user system using xdmcp, a local attacker could potentially use information available from the process list to brute force the key, allowing them to hijack other users' sessions. (CVE-2017-2625)
- It was discovered that libICE used a weak entropy to generate keys. A local attacker could potentially use this flaw for session hijacking using the information available from the process list. (CVE-2017-2626)
SolutionUpdate the affected packages.
