Description

This security bulletin contains information about 9 secuirty vulnerabilities.


1) Reachable Assertion (CVE-ID: CVE-2018-11782)

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

The vulnerability exists due to a reachable assertion when handling svnserve 'get-deleted-rev' requests. A remote authenticated attacker with read-only permissions can make the server to reply with incorrect revision number that will lead to svnserve crash.


2) Memory leak (CVE-ID: CVE-2019-19956)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in xmlParseBalancedChunkMemoryRecover in parser.c. A remote attacker can trigger a memory leak related to newDoc->oldNs and perform denial of service attack.


3) Memory leak (CVE-ID: CVE-2019-20388)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in xmlSchemaPreRun in xmlschemas.c. A remote attacker can trigger a xmlSchemaValidateStream memory leak and perform denial of service attack.


4) Infinite loop (CVE-ID: CVE-2020-7595)

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

The vulnerability exists due to infinite loop in xmlStringLenDecodeEntities in parser.c. A remote attacker can consume all available system resources and cause denial of service conditions in a certain end-of-file situation.


5) Out-of-bounds write (CVE-ID: CVE-2019-5094)

The vulnerability allows a local user to escalate privileges on the vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the quota file functionality. A local user can send a specially crafted xt4 partition, trigger out-of-bounds write on the heap and execute arbitrary code on the target system.

Note: An attacker can corrupt a partition to trigger this vulnerability.


6) Out-of-bounds write (CVE-ID: CVE-2019-5188)

The vulnerability allows a local user to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the directory rehashing functionality in "rehash.c" within the "mutate_name()" function. A local user can use a specially crafted ext4 directory, trigger out-of-bounds write on the stack and execute arbitrary code on the target system.


7) Input validation error (CVE-ID: CVE-2017-12652)

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

The vulnerability exists due to insufficient validation of user-supplied input in libpng when checking the chuck length against the user limit. A remote attacker can supply a specially crafted PNG image and crash the affected application.


8) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-11068)

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to an error within the xsltCheckRead() and xsltCheckWrite() functions when processing requests from remote servers. A remote attacker can trick the victim into opening a specially crafted URL that will result in "-1 error" code but the URL itself will be processed by the application later.

Successful exploitation of the vulnerability may allow an attacker to bypass certain security restrictions and perform XXE attacks.

9) Buffer overflow (CVE-ID: CVE-2019-18197)

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

The vulnerability exists due to a boundary error within the xsltCopyText() function in transform.c in libxslt. A remote attacker can create a specially crafted XML document, pass it to the affected application, trigger memory corruption and execute arbitrary code on the target system.

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