TeX Live SyncTeX Parser Heap Use-After-Free via Malformed SyncTeX File

The SyncTeX parser (synctex_parser.c) shipped with TeX Live and embedded by downstream consumers such as GNOME Evince contains a heap use-after-free vulnerability that allows attackers to crash applications or potentially execute arbitrary code by supplying a malformed .synctex or .synctex.gz file. A malformed SyncTeX file can construct a ref node with a NULL parent pointer, causing the replacement routine to fail to detach the node from its sibling chain, which triggers recursive freeing of live tree nodes and leaves dangling pointers that are later accessed by the parser during document load.

CVE-2023-46051

TeX Live 944e257 allows a NULL pointer dereference in texk/web2c/pdftexdir/tounicode.c. NOTE: this is disputed because it should be categorized as a usability problem.

CVE-2023-46048

Tex Live 944e257 has a NULL pointer dereference in texk/web2c/pdftexdir/writet1.c. NOTE: this is disputed because it should be categorized as a usability problem.

CVE-2024-25262

texlive-bin commit c515e was discovered to contain heap buffer overflow via the function ttfLoadHDMX:ttfdump. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted TTF file.

CVE-2023-32700

LuaTeX before 1.17.0 allows execution of arbitrary shell commands when compiling a TeX file obtained from an untrusted source. This occurs because luatex-core.lua lets the original io.popen be accessed. This also affects TeX Live before 2023 r66984 and MiKTeX before 23.5.

CVE-2023-32668

LuaTeX before 1.17.0 allows a document (compiled with the default settings) to make arbitrary network requests. This occurs because full access to the socket library is permitted by default, as stated in the documentation. This also affects TeX Live before 2023 r66984 and MiKTeX before 23.5.
