eBook-speaker 6.1.0 through 6.2.0 contains a stack buffer overflow vulnerability in get attributes() in src/common.c caused by an unbounded strcpy of an element's name attribute. Attackers can craft an EPUB or DAISY book with a name attribute of 511 or more characters to corrupt the stack and crash the reader when opened.

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified) Description: The issue is related to a bug in the speakup component of the Linux kernel, where the code uses sizeof() instead of ARRAY SIZE() when handling an array of u16 values. This can lead to an out-of-bounds condition. The exploitation of this issue may allow an attacker to cause a denial of service. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

The issue is related to the speakup component in the Linux kernel, which can cause a crash when a console is set up with a very large size and contains a word longer than 256 characters. This can lead to a denial of service. The vulnerability is associated with memory corruption in the get word() function.

The default configuration of xterm enables the allowWindowOps resource, which allows user-assisted attackers to execute arbitrary code or have unspecified other impact via escape sequences.
