Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2024-55549)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in xsltGetInheritedNsList. A remote attacker can pass specially crafted input to the application, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Use-after-free (CVE-ID: CVE-2025-24855)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in numbers.c when handling nested XPath evaluations. A remote attacker can pass specially crafted XML input to the application, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
3) NULL pointer dereference (CVE-ID: CVE-2023-2953)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the ber_memalloc_x() function. A remote attacker can send specially crafted data to the application and perform a denial of service (DoS) attack.
4) Improper locking (CVE-ID: CVE-2023-53107)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper locking within the veth_convert_skb_to_xdp_buff() function in drivers/net/veth.c. A local user can perform a denial of service (DoS) attack.
5) Improper Encoding or Escaping of Output (CVE-ID: CVE-2024-52005)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper input validation when handling ANSI escape sequences in messages passed via sideband channel. A remote attacker can pass specially crafted messages to the terminal and potentially execute untrusted scripts.
6) Security features bypass (CVE-ID: CVE-2025-0650)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to improper handling of UDP packets. A remote attacker can send specially crafted UDP packets that bypass egress access control lists (ACLs) in OVN installations and gain unauthorized access to virtual machines and containers running on the OVN network.
Successful exploitation of the vulnerability requires that ACLs on OVN installations are configured with a logical switch with DNS records set on it and if the same switch has any egress ACLs configured.
