Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2013-0340)
The vulnerability allows remote attackers to cause a denial of service attack.
The vulnerability exists due to insufficient validation of user-supplied input within the expat library, when processing XML files. A remote attacker can pass specially crafted XML content to the affected library and perform a denial of service (DoS) attack.2) Resource exhaustion (CVE-ID: CVE-2021-45960)
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 in the storeAtts() function in xmlparse.c. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Integer overflow (CVE-ID: CVE-2021-46143)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the doProlog() function in xmlparse.c. 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.
4) Integer overflow (CVE-ID: CVE-2022-22822)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the addBinding() function in xmlparse.c. 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.
5) Integer overflow (CVE-ID: CVE-2022-22823)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the build_model() function in xmlparse.c. 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.
6) Integer overflow (CVE-ID: CVE-2022-22824)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the defineAttribute() function in xmlparse.c. 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.
7) Integer overflow (CVE-ID: CVE-2022-22825)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the lookup() function in xmlparse.c. 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.
8) Integer overflow (CVE-ID: CVE-2022-22826)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the nextScaffoldPart() function in xmlparse.c. 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.
9) Integer overflow (CVE-ID: CVE-2022-22827)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the storeAtts() function in xmlparse.c. 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.
10) Integer overflow (CVE-ID: CVE-2022-23990)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the doProlog() function. 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.
11) Stack-based buffer overflow (CVE-ID: CVE-2022-25313)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in build_model. A remote unauthenticated attacker can trigger 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.
12) Integer overflow (CVE-ID: CVE-2022-25314)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in copyString. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
13) Use-after-free (CVE-ID: CVE-2022-43680)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
14) Resource exhaustion (CVE-ID: CVE-2023-52425)
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 parsing large tokens. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
