Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-1335-1)
Summary:	The remote host is missing an update for the Debian 'zsh' package(s) announced via the DLA-1335-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'zsh' package(s) announced via the DLA-1335-1 advisory. Vulnerability Insight: Two security vulnerabilities were discovered in the Z shell. CVE-2018-1071 Stack-based buffer overflow in the exec.c:hashcmd() function. A local attacker could exploit this to cause a denial of service. CVE-2018-1083 Buffer overflow in the shell autocomplete functionality. A local unprivileged user can create a specially crafted directory path which leads to code execution in the context of the user who tries to use autocomplete to traverse the before mentioned path. If the user affected is privileged, this leads to privilege escalation. For Debian 7 Wheezy, these problems have been fixed in version 4.3.17-1+deb7u2. We recommend that you upgrade your zsh packages.

Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
