Description

This security bulletin contains information about 15 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2025-22868)

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

The vulnerability exists due to the jws package does not properly control consumption of internal resources when handling malformed tokens. A remote attacker can pass a malformed JWT token to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Resource exhaustion (CVE-ID: CVE-2025-30204)

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

The vulnerability exists due to application does not properly control consumption of internal resources within the parse.ParseUnverified function when parsing authorization header. A remote attacker can send a specially crafted HTTP response to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.


3) Out-of-bounds write (CVE-ID: CVE-2019-12900)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the BZ2_decompress() function in decompress.c. A remote attacker can create a specially crafted archive, trick the victim into opening it using the affected library, trigger out-of-bounds write and execute arbitrary code on the target system.

4) Cross-site scripting (CVE-ID: CVE-2020-11023)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when passing <option> elements to jQuery’s DOM manipulation methods. A remote attacker can execute arbitrary JavaScript code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


5) Stack-based buffer overflow (CVE-ID: CVE-2024-8176)

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

The vulnerability exists due to a boundary error when handling XML content. A remote attacker can pass specially crafted XML content to the application, 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.


6) Resource exhaustion (CVE-ID: CVE-2024-11187)

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

The vulnerability exists due to application does not properly control consumption of internal resources when handling DNS zones with numerous records in the Additional section. A remote attacker can trigger resource exhaustion by sending multiple queries to he affected server and perform a denial of service (DoS) attack.


7) Path traversal (CVE-ID: CVE-2024-12087)

The vulnerability allows a remote server to write files to arbitrary locations on the system.

The vulnerability exists due to input validation error when using "--inc-recursive" option. A remote attacker can can trick the victim into connecting to a rouge rsync server and write arbitrary files to arbitrary locations on the client system.


8) Path traversal (CVE-ID: CVE-2024-12088)

The vulnerability allows a remote server to write files to arbitrary locations on the system.

The vulnerability exists due to input validation error when using "--safe-links" option. A remote attacker can can trick the victim into connecting to a rouge rsync server and write arbitrary files to arbitrary locations on the client system.

9) Resource exhaustion (CVE-ID: CVE-2024-12133)

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

The vulnerability exists due to application does not properly control consumption of internal resources processing a large number of SEQUENCE OF or SET OF elements in a certificate. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


10) Resource exhaustion (CVE-ID: CVE-2024-12243)

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

The vulnerability exists due to libtasn1 does not properly control consumption of internal resources when decoding certain DER-encoded certificate data. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


11) Race condition (CVE-ID: CVE-2024-12747)

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to a race condition when handling symbolic links. A local user can replace a file with a symbolic link, bypass implemented protection in rsync that prevents software from following symbolic links and read contents of arbitrary files on the system with elevated privileges.


12) Use-after-free (CVE-ID: CVE-2024-56171)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the xmlSchemaIDCFillNodeTables() and xmlSchemaBubbleIDCNodeTables() functions in xmlschemas.c. A remote attacker can pass specially crafted XML document 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.


13) Buffer overflow (CVE-ID: CVE-2025-0395)

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

The vulnerability exists due to a boundary error when the assert() function fails. A remote attacker can trigger memory corruption and perform a denial of service (DoS) attack.


14) Out-of-bounds write (CVE-ID: CVE-2025-24528)

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

The vulnerability exists due to a boundary error when calculating ulog block size in kadmind. A remote user can trigger an out-of-bounds write and perform a denial of service (DoS) attack.


15) Stack-based buffer overflow (CVE-ID: CVE-2025-24928)

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

The vulnerability exists due to a boundary error within the xmlSnprintfElements() function in valid.c. A remote attacker can pass specially crafted XML data to the application, 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.
