Heap use-after-free in the SyncTeX parser shipped with TeX Live and embedded by GNOME Evince allows crash or potential arbitrary code execution when a user opens a malformed .synctex or .synctex.gz file. The flaw stems from a NULL parent pointer condition in _synctex_post_process_ref() that bypasses node detachment, causing recursive freeing of live tree nodes and leaving dangling pointers later accessed during document parsing. Exploitation requires local file access and active user interaction (UI:A per CVSS 4.0), no public exploit has been confirmed, but a detailed researcher blog post by the discoverer (Fatih Çelik) is publicly available and the RCE tag suggests demonstrated impact potential.
LuaTeX before 1.17.0 allows execution of arbitrary shell commands when compiling a TeX file obtained from an untrusted source. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. This Command Injection vulnerability could allow attackers to inject arbitrary commands into system command execution.
LuaTeX before 1.17.0 allows a document (compiled with the default settings) to make arbitrary network requests. Rated medium severity (CVSS 5.5), this vulnerability is no authentication required, low attack complexity. Public exploit code available.
An issue was discovered in t1_check_unusual_charstring functions in writet1.c files in TeX Live before 2018-09-21. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. This Buffer Overflow vulnerability could allow attackers to corrupt memory to execute arbitrary code or crash the application.
TeX Live through 20170524 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
TeX Live allows remote attackers to execute arbitrary commands by leveraging inclusion of mpost in shell_escape_commands in the texmf.cnf config file. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and EPSS exploitation probability 10.6%.
