Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2026-25749)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the get_tagfname() function in src/tag.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Stack-based buffer overflow (CVE-ID: CVE-2026-26269)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the special_keys() function in src/netbeans.c. A remote attacker can trick the victim into opening a specially crafted file that initiates connection with attacker-controlled NetBeans server, trigger a stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


3) Heap-based buffer overflow (CVE-ID: CVE-2026-28418)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the emacs_tags_new_filename() function in Emacs-style tags file parsing logic. A remote attacker can trick the victim into opening a specially crafted tags file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Heap-based buffer overflow (CVE-ID: CVE-2026-28419)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the emacs_tags_parse_line() function in src/tag.c in Emacs-style tags file parsing logic. A remote attacker can trick the victim into opening a specially crafted tags file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


5) Heap-based buffer overflow (CVE-ID: CVE-2026-28420)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the handle_pushline() function in src/terminal.c processing maximum combining characters from Unicode supplementary planes. A remote attacker can trick the victim into copying a specially crafted string into the :terminal buffer, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


6) Heap-based buffer overflow (CVE-ID: CVE-2026-28421)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in swap file recovery logic. A remote attacker can trick the victim into opening a specially crafted swap file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


7) Stack-based buffer overflow (CVE-ID: CVE-2026-28422)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the build_stl_str_hl() function. A remote unauthenticated attacker can trick the victim into opening a specially crafted file, trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
