Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Use of uninitialized resource (CVE-ID: CVE-2025-15281)

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

The vulnerability exists due to usage of uninitialized resources when calling wordexp with WRDE_REUSE in conjunction with WRDE_APPEND. A remote attacker can pass specially crafted data to the application, trigger an uninitialized usage of resources and crash the application. 


2) Integer overflow (CVE-ID: CVE-2026-0861)

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

The vulnerability exists due to integer overflow within the memalign functions, such as memalign(), posix_memalign(),  aligned_alloc(). A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.

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


3) Use of uninitialized resource (CVE-ID: CVE-2026-0915)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to usage of uninitialized resources when calling getnetbyaddr() or getnetbyaddr_r() functions with a configured nsswitch.conf and "net==0" in _nss_dns_getnetbyaddr_r. A remote attacker can trick the victim to initiate queries and force the library to leak contents to the configured DNS resolver.
