In libass 0.14.0, the call to assoutlineconstruct's outlinestroke function causes a signed integer overflow...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: ipv6: Fixed an issue of signed integer overflow in l2tpip6sendmsg. When len = INTMAX - transhdrlen, the value of ulen = len + transhdrlen will cause an overflow. To address this issue, we can follow the approach used by udpv6 and...

The Samba AD DC administration tool, when working against a remote LDAP server, will, by default, send new or reset passwords over a signed-only connection...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: arm64: cacheinfo: Fixed the incorrect assignment of a signed error value to unsigned fwlevel. Although the acpifindlastcachelevel function always returns a signed value, and the documentation states that it will return any errors...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Regulator: Core – Prevent integer underflow By using a ratio of delay to pollEnabledTime that is not an integer, timeRemaining underflows may occur, causing the loop not to exit as expected. Since delay can be derived from DT, an...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: dsi: Prevent underflow when calculating packet sizes. Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could lead to an underflow, causing the value to wrap around t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mptcp: Ensure that the tx-skbs always have the MPTCP extensions. Due to signed/unsigned comparison, the expression: info-sizegoal - skb-len 0 evaluates to true when the size goal is smaller than the skb size. This results in a la...

Astra Linux – Vulnerability in Thunderbird

When viewing an email message A, which contains an attached message B, where B is encrypted or digitally signed, or both, Thunderbird may display incorrect encryption or signature statuses. After opening and viewing the attached message B, when returning to the display of message A, message A may...

Astra Linux – Vulnerability in Thunderbird

When processing a PGP/MIME payload that contains digitally signed text, the first paragraph of the text is never displayed to the user. This is because the text is interpreted as a MIME message, and the first paragraph is always treated as part of an email header section. A digitally signed text...

Astra Linux – Vulnerability in libsndfile

Multiple signed integer overflows occur in the aureadheader function in src/au.c, as well as in the mat4open and mat4readheader functions in src/mat4.c within Libsndfile. This vulnerability allows an attacker to cause a Denial of Service or other unspecified impacts...

Astra Linux – Vulnerability in FLAC
