Stack-based buffer overflow in the parse_identifier function in tgsi_text.c in the TGSI auxiliary module in the Gallium driver in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (out-of-bounds array access and QEMU process crash) via vectors related to parsing properties.

The remote host is affected by the vulnerability described in GLSA-201707-06 (virglrenderer: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in virglrenderer. Please       review the CVE identifiers referenced below for details.
  Impact :

    A local attacker could cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

This update for virglrenderer fixes the following issues :
