**Name of the Vulnerable Software and Affected Versions** Xpdf versions 4.05 and earlier **Description** The issue arises from invalid header information in a DCT (JPEG) stream, leading to an uninitialized variable in the DCT decoder. This can cause a segfault when attempting to read from an invalid address. A proof-of-concept PDF file has been identified as triggering this issue. **Recommendations** For Xpdf versions 4.05 and earlier, consider updating to a newer version to mitigate the risk, as the current version contains an uninitialized variable in the DCT decoder that can lead to a segfault. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Foxit PDF Reader version 11.2.1.53537 **Description** This issue allows remote attackers to disclose sensitive information on affected installations. User interaction is required to exploit this, where the target must visit a malicious page or open a malicious file. The flaw exists within the handling of Annotation objects. By performing actions in JavaScript, an attacker can trigger a read past the end of an allocated object. This can be leveraged in conjunction with other issues to execute arbitrary code in the context of the current process. **Recommendations** For Foxit PDF Reader version 11.2.1.53537, consider disabling the handling of Annotation objects in JavaScript until a patch is available. Restrict access to malicious pages or files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.

**Name of the Vulnerable Software and Affected Versions** Foxit PDF Reader version 11.2.1.53537 **Description** This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the `deletePages` method due to the lack of validating the existence of an object prior to performing operations on it. An attacker can leverage this to execute code in the context of the current process. **Recommendations** For Foxit PDF Reader version 11.2.1.53537, as a temporary workaround, consider disabling the `deletePages` method until a patch is available. Restrict access to potentially malicious files or web pages to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
