Background ========= A shell designed for interactive use, although it is also a powerful scripting language. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-shells/zsh < 5.6 > = 5.6 Description ========== Two input validation errors have been discovered in how Zsh parses scripts: * Parsing a malformed shebang line could cause Zsh to call a program listed in the second line (CVE-2018-0502) * Shebang lines longer than 64 characters are truncated (CVE-2018-13259) Impact ===== An attacker could entice a user to execute a specially crafted script using Zsh, possibly resulting in execution of arbitrary code with the privileges of the process. Workaround ========= There is no known workaround at this time. Resolution ========= All Zsh users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =app-shells/zsh-5.6" References ========= [ 1 ] CVE-2018-0502 https://nvd.nist.gov/vuln/detail/CVE-2018-0502 [ 2 ] CVE-2018-13259 https://nvd.nist.gov/vuln/detail/CVE-2018-13259 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/201903-02 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
