Arch Linux Security Advisory ASA-201812-4

Severity: High
Date : 2018-12-08
CVE-ID : CVE-2018-17407
Package : texlive-bin
Type : arbitrary code execution
Remote : No
Link : https://security.archlinux.org/AVG-770

Summary

The package texlive-bin before version 2018.48691-1 is vulnerable to
arbitrary code execution.

Resolution

Upgrade to 2018.48691-1.

pacman -Syu “texlive-bin>=2018.48691-1”

The problem has been fixed upstream in version 2018.48691.

Workaround

None.

Description

An issue was discovered in t1_check_unusual_charstring functions in
writet1.c files in TeX Live before 2018-09-21. A buffer overflow in the
handling of Type 1 fonts allows arbitrary code execution when a
malicious font is loaded by one of the vulnerable tools: pdflatex,
pdftex, dvips, or luatex.

Impact

A local attacker can execute arbitrary code via a crafted font.
