Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2025-68973)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error within the armor_filter() function in g10/armor.c. A remote attacker can pass specially crafted input to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.


2) Out-of-bounds write (CVE-ID: CVE-2025-9230)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when trying to decrypt CMS messages encrypted using password based encryption. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.

Successful exploitation of the vulnerability requires that password based (PWRI) encryption support in CMS messages is enabled. 


3) Out-of-bounds read (CVE-ID: CVE-2025-9086)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition when reading cookie path. A malicious server can set a specially crafted cookie path using the secure keyword, trigger an out-of-bounds read error and crash the application.


4) Integer overflow (CVE-ID: CVE-2025-13601)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to integer overflow within the g_escape_uri_string() function. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and perform a denial of service attack. 


5) Heap-based buffer overflow (CVE-ID: CVE-2025-11083)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the elf_swap_shdr() function in bfd/elfcode.h. A local user can trigger a heap-based buffer overflow and execute arbitrary code on the target system.


6) Off-by-one (CVE-ID: CVE-2023-47038)

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

The vulnerability exists due to an off-by-one error when processing regular expressions. A remote attacker can trigger an off-by-one error and execute arbitrary code on the target system.

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