CRITICAL9.8

xterm before 375 allows code execution via font ops, e.g., because an OSC 50 response may have Ctrl-g and therefore lead to command execution within the vi line-editing mode of Zsh. NOTE: font ops are not allowed in the xterm default configurations of some Linux distributions.

Package update xterm in branch p10

Closed issues (3)

Уязвимость функции set_sixel компонента graphics_sixel.c эмулятора терминала XTerm, позволяющая нарушителю вызвать отказ в обслуживании

xterm through Patch 370, when Sixel support is enabled, allows attackers to trigger a buffer overflow in set_sixel in graphics_sixel.c via crafted text.

xterm before 375 allows code execution via font ops, e.g., because an OSC 50 response may have Ctrl-g and therefore lead to command execution within the vi line-editing mode of Zsh. NOTE: font ops are not allowed in the xterm default configurations of some Linux distributions.
