Title
Read one byte past a buffer when normalizing Unicode
Summary
Heimdal is an implementation of ASN.1/DER, PKIX, and Kerberos. Versions prior to 7.7.1 are vulnerable to a denial of service vulnerability in Heimdal's PKI certificate validation library, affecting the KDC (via PKINIT) and kinit (via PKINIT), as well as any third-party applications using Heimdal's libhx509. Users should upgrade to Heimdal 7.7.1 or 7.8. There are no known workarounds for this issue.

Summary
A heap out-of-bounds read vulnerability exists in the RLA format parser of OpenImageIO master-branch-9aeece7a and v2.3.19.0. More specifically, in the way run-length encoded byte spans are handled. A malformed RLA file can lead to an out-of-bounds read of heap metadata which can result in sensitive information leak. An attacker can provide a malicious file to trigger this vulnerability.

Summary
A stack-based buffer overflow vulnerability exists in the IGXMPXMLParser::parseDelimiter functionality of Accusoft ImageGear 19.10. A specially-crafted PSD file can overflow a stack buffer, which could either lead to denial of service or, depending on the application, to an information leak. An attacker can provide a malicious file to trigger this vulnerability.

Summary
An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport, respectively, if data_count == block_size. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.

Mitigation
Implementation
When copying character arrays or using character manipulation methods, the correct size parameter must be used to account for the null terminator that needs to be added at the end of the array. Some examples of functions susceptible to this weakness in C include strcpy(), strncpy(), strcat(), strncat(), printf(), sprintf(), scanf() and sscanf().
