ckolivas lrzip strtol_l.c __GI_____strtol_l_internal null pointer dereference

A security flaw has been discovered in ckolivas lrzip up to 0.651. This impacts the function __GI_____strtol_l_internal of the file strtol_l.c. Performing manipulation results in null pointer dereference. The attack is only possible with local access. The exploit has been released to the public and may be exploited.

The join_pthread function in stream.c in liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted archive.

The read_1g function in stream.c in liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted archive.

The lzo1x_decompress function in lzo1x_d.ch in LZO 2.08, as used in lrzip 0.631, allows remote attackers to cause a denial of service (invalid memory read and application crash) via a crafted archive.

The read_stream function in stream.c in liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial of service (use-after-free and application crash) via a crafted archive.

The bufRead::get() function in libzpaq/libzpaq.h in liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted archive.

In lrzip 0.631, a stack buffer overflow was found in the function get_fileinfo in lrzip.c:979, which allows attackers to cause a denial of service via a crafted file.

In lrzip 0.631, a stack buffer overflow was found in the function get_fileinfo in lrzip.c:1074, which allows attackers to cause a denial of service via a crafted file.

The bufRead::get() function in libzpaq/libzpaq.h in liblrzip.so in lrzip 0.631 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted archive.

lrzip v0.651 was discovered to contain a heap overflow via the libzpaq::PostProcessor::write(int) function at /libzpaq/libzpaq.cpp. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted file.

Lrzip v0.651 was discovered to contain multiple invalid arithmetic shifts via the functions get_magic in lrzip.c and Predictor::init in libzpaq/libzpaq.cpp. These vulnerabilities allow attackers to cause a Denial of Service via unspecified vectors.

lrzip v0.641 was discovered to contain a multiple concurrency use-after-free between the functions zpaq_decompress_buf() and clear_rulist(). This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted Irz file.

An issue was discovered in lrzip version 0.641. There is a use-after-free in ucompthread() in stream.c:1538.

An issue was discovered in lrzip version 0.641. There are memory leaks in fill_buffer() in stream.c.

Use after free in lzma_decompress_buf function in stream.c in Irzip 0.631 allows attackers to cause Denial of Service (DoS) via a crafted compressed file.

A null pointer dereference was discovered in ucompthread in stream.c in Irzip 0.631 which allows attackers to cause a denial of service (DOS) via a crafted compressed file.

A null pointer dereference was discovered lzo_decompress_buf in stream.c in Irzip 0.621 which allows an attacker to cause a denial of service (DOS) via a crafted compressed file.

The lzo1x_decompress function in liblzo2.so.2 in LZO 2.10, as used in Long Range Zip (aka lrzip) 0.631, allows remote attackers to cause a denial of service (invalid memory read and application crash) via a crafted archive, a different vulnerability than CVE-2017-8845.

In Long Range Zip (aka lrzip) 0.631, there is an infinite loop in the runzip_fd function of runzip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted lrz file.

In Long Range Zip (aka lrzip) 0.631, there is an infinite loop and application hang in the get_fileinfo function (lrzip.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted lrz file.
