Description

This security bulletin contains information about 4 vulnerabilities.


1) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2025-49506)

CWE-ID: CWE-208 - Information Exposure Through Timing Discrepancy

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to observable timing discrepancies in apr_password_validate() when comparing password hashes or passwords. A remote attacker can measure response times to infer sensitive information and disclose sensitive information.

The issue is particularly relevant on platforms without crypt() support, such as Windows, BeOS, NetWare, or Android.


2) Uncontrolled Recursion (CVE-ID: CVE-2026-32327)

CWE-ID: CWE-674 - Uncontrolled Recursion

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled recursion in apr_xml_quote_elem() when parsing XML from untrusted sources. A remote attacker can supply crafted XML input to cause a denial of service.

The issue affects library consumers that parse XML from untrusted sources and use the vulnerable function.


3) SQL injection (CVE-ID: CVE-2026-34191)

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform SQL injection.

The vulnerability exists due to improper neutralization of special elements used in an SQL command in the apr_dbd_oracle provider when processing SQL commands. A remote attacker can supply crafted input to perform SQL injection.


4) Heap-based buffer overflow (CVE-ID: CVE-2026-34502)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to heap-based buffer overflow in the apr memcached client when processing memcached responses. A remote attacker can send specially crafted responses to cause a denial of service.
