CVE-2006-10003 (GCVE-0-2006-10003)

Title
XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in st_serial_stack
Summary
XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in st_serial_stack.
In the case (stackptr == stacksize - 1), the stack will NOT be expanded. Then the new value will be written at location (++stackptr), which equals stacksize and therefore falls just outside the allocated buffer.
The bug can be observed when parsing an XML file with very deep element nesting
Severity ?

Title
XML::Parser versions through 2.47 for Perl could overflow the pre-allocated buffer size cause a heap corruption (double free or corruption) and crashes
Summary
XML::Parser versions through 2.47 for Perl could overflow the pre-allocated buffer size cause a heap corruption (double free or corruption) and crashes.
A :utf8 PerlIO layer, parse_stream() in Expat.xs could overflow the XML input buffer because Perl's read() returns decoded characters while SvPV() gives back multi-byte UTF-8 bytes that can exceed the pre-allocated buffer size. This can cause heap corruption (double free or corruption) and crashes.

Title
YAML::Syck versions through 1.36 for Perl has several potential security vulnerabilities including a high-severity heap buffer overflow in the YAML emitter
Summary
YAML::Syck versions through 1.36 for Perl has several potential security vulnerabilities including a high-severity heap buffer overflow in the YAML emitter.
The heap overflow occurs when class names exceed the initial 512-byte allocation.
The base64 decoder could read past the buffer end on trailing newlines.
strtok mutated n->type_id in place, corrupting shared node data.
A memory leak occurred in syck_hdlr_add_anchor when a node already had an anchor. The incoming anchor string 'a' was leaked on early return.
Severity ?

Title
YAML::Syck versions before 1.36 for Perl has missing Null-Terminators which causes Out-of-Bounds Read and potential Information Disclosure
Summary
YAML::Syck versions before 1.36 for Perl has missing null-terminators which causes out-of-bounds read and potential information disclosure
Missing null terminators in token.c leads to but-of-bounds read which allows adjacent variable to be read
The issue is seen with complex YAML files with a hash of all keys and empty values. There is no indication that the issue leads to accessing memory outside that allocated to the module.
Severity ?
6.5 (Medium)
CWE
- CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer
